Purdue University ResNet Guide

1. Before You Get Started

With a ResNet (Residence Network Services) subscription, students living in Purdue University Residences may connect their personal computers to any authorized campus computing resource using industry standard 10base-T Ethernet interfaces. Also, students, faculty, and staff living off campus may have the same type of access via dial-up or Verizon ADSL service. This guide provides information that will help subscribers using Ethernet or DSL establish and use their connections. Set-up procedures for off-campus dial-up connections can be found in the ResNet Off-Campus Dial-up Guide available in MATH 231.

As a subscriber to ResNet, it is your responsibility to provide your own "network ready" personal computer. You will probably need to purchase a network adapter (also known as a network interface card or NIC) in order to make your computer network ready. The adapter must be compatible with your computer and have an RJ-45, 10base-T Ethernet network connector. You will also need to provide an industry standard category 5 (CAT 5), twisted-pair jumper cable long enough to reach the ResNet outlet on the wall of your room or your ADSL modem. Students living on campus may purchase jumper cables from the main office of your residence.

Required Equipment for IBM compatible PCs

Unfortunately, many older models of PCs are not adequate for use as network clients. Therefore, the following requirements are offered as the minimum for which you may expect reasonable performance from your machine as well as the minimum configuration for which we can offer support.

System Component Minimum DesirableProcessor Pentium Pentium II or laterRAM 32 Mb 128 Mb or moreHard Disk Capacity 4 GB 10 GB or moreOperating System Windows 95 Windows 98 or later

When you purchase a NIC, we recommend that you keep your receipt and packaging so that the card can be returned in the event that it proves to be incompatible with your machine. If you install your NIC prior to arriving at Purdue, please keep the driver diskette(s) with your machine. You will need the diskette(s) if you experience problems and need to re-install the driver. Also, in order to install the driver for your NIC, you must have your Windows CDROM with you at the time of installation. All driver installations require access to the same ".cab" files that the operating system was installed from (which are located on the Windows CDROM). There are several different

Revised 7/10/01 Page 1

Purdue University ResNet Guideversions of the Windows CDROM and attempting to use someone else's CDROM for this purpose may corrupt your system files.

Although we do not require anyone to purchase a specific adapter, the Computing Center does not have experience with or documentation for every network adapter that you could possibly purchase. Therefore, we suggest that you purchase one of the adapters listed below if you are not comfortable with your own ability to troubleshoot problems that may arise with your equipment. Should you encounter a problem, the Computing Center staff will attempt to help you, but the functionality of your equipment is ultimately your own responsibility.

3COM Etherlink 10/100 PCI(3C905B-TX-NM)

For desktop system with PCI bus

3COM Megahertz 10/100(3CXFE575CT)

For laptop with PCMCIA slot

Linksys Etherfast 10/100 LAN Card(LNE100TX)


Linksys Etherfast 10/100 PC Card(PCMPC100)

For laptop with PCMCIA slot

NETGEAR Fast Ethernet PCI adapter(FA310TX)


SMC EZ Card 10/100(SMC1211TX)


Most of these cards are for use in desktop systems that have PCI bus slots available. Cards for use in ISA slots are still generally available, but they now tend to be more expensive than the PCI versions and they are typically harder to configure.

Required Equipment for Macintosh PCs

Unfortunately, many older models of Mac's are not adequate for use as network clients. Therefore, the following requirements are offered as the minimum for which you may expect reasonable performance from your machine. We are only able to offer limited support for Macintosh machines.



System Component

Minimum Desirable

Processor 68040 Power PC or laterRAM 16 Mb 32 Mb or moreHard Disk Capacity 200 Mb 1 GB or moreOperating System System 7.5.3 System 7.5.3 or later

Due to the improved network features of "Open Transport", it is recommended that anyone using a MacOS earlier than System 7.5.3 upgrade to 7.5.3 or later.

You will have to refer to your system's documentation to determine what type of network adapter you will need to make your machine compatible with the 10base-T network connection provided by ResNet. If needed, we recommend that you purchase a Farallon adapter such as:

PN502a AAUI to UTP transceiver for many systems with onboard Ethernet

PN592a-TP NIC for LC family

PN590a-TP NIC for MAC II family

If you do not know which type of adapter to purchase for your specific machine, Farallon has an excellent Ethernet product selector on their web site at http://www.farallon.com/products/selector/. Please make certain that the product you purchase is the correct type for your model of computer.

2. Program Responsibilities

The success of the on-campus ResNet service is dependent upon the combined efforts of the University Residence staff, the Purdue University Computing Center (PUCC), and the network subscriber. The success of the off-campus ResNet service is dependent upon the combined efforts of Verizon Network Services, PUCC, and the network subscriber. By understanding the responsibilities of each of these entities you will be in a better position to seek help should you encounter problems.

University Residences

The managers and their staffs administer the on-campus ResNet service. They process the ResNet subscription requests, submit and track all orders for installation and removal of service, and handle billing/refund issues. If you have questions regarding the subscription process, contact the main office of your residence.


http://www.farallon.com/products/selector/


Verizon Network Services

Verizon provides the ADSL transport portion of the ResNet service for off-campus high-speed network access. Verizon handles all billing and service related issues for this portion of the service. Contact information for Verizon is sent to each subscriber, along with his/her IP address information, via e-mail from ResNet, when they sign up for off-campus ADSL service.

Purdue University Computing Center (PUCC)

The Computing Center's Purdue Data Network division (PDN) is responsible for maintaining the overall functionality of the network at Purdue. Upon receiving requests from the residence hall staffs, PDN staff members perform the activation/deactivation of the network connections to student rooms. PDN also provides technical assistance to subscribers (both on and off campus) that experience difficulties with establishing their network connection. The Computing Center does NOT provide repair services or general software consulting for non-university owned computers.

PUCC staff members never visit off-campus residences for the purpose of servicing ResNet related issues. On campus, PDN oversees the activities of the Resident Computing Consultants (RCC) and dispatches a technician or network engineer in the event that an RCC is unable to resolve a problem.

Network Subscriber

As a subscriber to ResNet services, you are entitled to the full benefits offered by the program. However, you are responsible for determining whether your equipment and software are suitable for use with the ResNet services and for maintaining their functionality. It is your responsibility to obtain and install the network adapter as well as necessary software needed to make your PC network ready. You will need to perform all setup of your equipment and software. It is also up to you to report any problems that you have with your ResNet service.

You must use the IP address that was assigned to you. If you have been a ResNet subscriber previously, do not attempt to use your previous IP address! Never try to use any other address for your machine. Use of an address that was not registered for your machine may interfere with someone else's use of the network and/or render your ResNet connection nonfunctional. Deliberate attempts to use an address different from that, which was assigned to you, are violations of PUCC policy that will not be tolerated and will be referred to the Dean of Students Office for appropriate action.

Once your ResNet connection is established, the entire World Wide Web is at your fingertips via the Internet. Your ResNet connection does, indeed, provide


Purdue University ResNet Guideyou worldwide communications for e-mail and information retrieval. This freedom to roam the world from your keyboard comes with equivalent responsibilities. It is your responsibility, as a member of the Purdue community, to abide by all rules and regulations associated with the use of Purdue University facilities. These include state and federal laws as well as Purdue University regulations and policies specified in the bulletin entitled University Regulations, which is available in the Dean of Students Office. You should consult the Dean of Students Office if you have any questions about the interpretation of a university regulation or policy. Also, read the PUCC document ZZ-POLICY for a description of PUCC policies. This document is available in paper form in the PUCC Information Center (MATH 231) or electronic form, via the World Wide Web, from the Computing Center's web site: http://www.purdue.edu/PUCC/. Violations of these rules and regulations will be dealt with by the proper authorities.

ResNet access to the Internet is a shared resource. PUCC may limit the amount of bandwidth that any one user may consume in order to fairly allocate resources among all ResNet users.

A few DO's and DON'Ts

Here are a few DOs and DON'Ts to help you understand what constitutes acceptable and unacceptable activity as a ResNet subscriber. This is not an exhaustive list, these are only a few examples. Read the policy documents, described above, for detailed information.

DO use common sense and good judgment while communicating with others on the network.

DO abide by all local, state, and federal laws as well as Purdue University regulations and policies. Violators DO get caught!

DO enjoy your connectivity without infringing on other's rights to the same enjoyment. Sending threatening e-mail, excessive amounts of e-mail ("mail bombing" or "SPAM"), or other attacks designed to deprive others of their rights to use the network without interference are not permitted.

DON'T try to start an on-line business. Use of ResNet to promote any commercial or non-Purdue sanctioned activity by e-mail, web site, or any other means is not permitted. If you absolutely must become an Internet entrepreneur, find an appropriate commercial site to host your activities.

DON'T distribute copyrighted material. Copyrighted material should never be distributed without the permission of the copyright owner. Posting material in any publicly accessible location is considered "intent to distribute". It is illegal to post or make available any program, image, audio or video files containing copyrighted material without the permission of the copyright owner. This includes, but is not limited to, copies of commercial software tools, games, and MP3 files.

DON'T distribute pornography or other illegal materials. Posting material in any publicly accessible location is considered "intent to distribute". Any


Purdue University ResNet Guideitems that you choose to distribute must conform to all local, state, and federal laws as well as Purdue University regulations and policies.

DON'T download or use pirated software, games, or other illegally posted materials. Be aware that these illegal downloads often contain viruses or other "trojan horse" software that may give a complete stranger control of your computer or access to all of your files.

Inappropriate use of your network connection will have consequences!

3. Installation Guidelines for IBM compatible Personal Computers

The best sources of detailed instructions for installing your equipment are the manuals that were packaged with the equipment. It is beyond the scope of this guide and simply not practical for us to try and provide detailed instructions for installation of network adapters and associated software drivers. Therefore, the following should be treated as general guidelines for the process of getting your machine operational as a client of the Purdue Data Network. Your machine must be fully functional prior to attempting the installation of a network adapter. If you are aware of any hardware or software problem(s) existing in your machine, correct the problem(s) before proceeding with this installation!

Hardware Installation

University personnel, including your RCCs, are not authorized to perform hardware installations in student owned computers. Therefore, if you need help with hardware installation, you will need to ask your computer vendor, an authorized service center, a family member, or friend to help you install your network adapter. To install the adapter in your machine:

1. Read the information supplied with the card. If there is something you do not understand, find someone that can help you figure it out (see "Getting Help" below) before attempting to install the card. Insure that any jumpers or switches that need to be set on the card are in the correct position.

2. Turn off your PC and disconnect the power.

3. Remove the cover from the machine.

4. Select an open expansion slot that is of the same type as the adapter that you are about to install. Refer to your system's manual if you are not sure which slot is the correct type. Remove the screw that secures the filler panel for that slot and remove the panel.



5. Carefully remove the adapter from its package and insert it into the empty slot. Be certain that the card is fully seated in the connector and properly aligned with the back panel. Then secure it with the screw removed from the filler panel in step 4.

One of the most common problems that we have found, when subscribers ask for help, is that they have not seated the card completely. When you press hard enough to seat the adapter, you should feel it go down into the socket.

6. Replace the system cover and reconnect the power.

[Subscribers that reside in locations where Ethernet is not available should refer to the section entitled “ResNet 1-Meg Modem (on-campus xDSL)” or “Verizon ADSL (off-campus)” in this document for cabling instructions.]

7. Connect the jumper cable between the connector on your network adapter and the ResNet outlet, on the wall of your room, which was assigned to you. If you are the first subscriber in your room, your outlet will typically be the one labeled with "-A" appended to the room number. If your roommate is also a ResNet subscriber, both the "-A" and "-B" outlets will be active. In this case, even though either outlet will work, you should still use the outlet that was assigned to you in order to avoid future complications. Do not attempt to use the "-1" or "-2" outlets. They are only used for telephone connections and do not work as data connections. In fact, use of these outlets could damage your Ethernet interface.

Software Installation

Turn on your PC and let it boot. If you have a PnP capable machine running Windows 95, the operating system should automatically detect the new card and install the drivers for it. If you are not running Windows 95 or your adapter is not PnP capable, you may have to run an installation procedure provided by the manufacturer. Read your manual and follow the manufacturer's instructions for installing the drivers for the adapter. [If you don't have a manual or installation diskette, then it may not be possible for us to help you even though we will do our best.] Once the drivers have been installed, you must tell your system what it is called (machine name) and where it can be found on the network (IP address). You also need to provide some other necessary information that is shown here as well as provided to you by the main office of your residence (on-campus) or by e-mail (off-campus).

Windows 9x

[The following instructions are specifically for the Windows 95 operating system. This procedure also applies to Windows 98 and Windows Me operating systems (minor differences are noted below).]



1. Right-click (click using the right mouse button) on the "Network Neighborhood" icon, then select "Properties" from the menu that is displayed. [In Windows Me, the “Network Neighborhood” icon has been renamed to “My Network Places”.]

-OR-

Click the "Start " button on your task bar and select "Control Panel" from the "Settings" menu. Then, double-click on the "Network" icon in the "Control Panel" window.

2. Look at the list of installed components on the "Configuration" tab of the "Network" properties sheet. Verify that there are entries which include the name of your network adapter, such as:

Realtek RTL8019 PnP LAN adapter or compatible TCP/IP

[Sometimes a NIC is sold under more than one brand name. Windows 95 may recognize your card as being a different brand than that which you purchased. The above example is for a "Genius LAN" card that shows up as a Realtek.]

If your machine has more than one adapter installed (which will be the case if you have a Dialup adapter or AOL adapter already installed), the TCP/IP entry will include the name of your adapter like that shown in the graphic. If your adapter card does not show up in this list, then the drivers were not installed – go back and install the drivers first.



3. Select the TCP/IP entry that includes the name of your adapter card (if any) by clicking on the entry, then click the "Properties" button. If the TCP/IP entry is missing, see "Troubleshooting" below. Only perform the following steps in the TCP/IP properties for your Ethernet card. The TCP/IP properties for all other adapters should be set to “Obtain an IP address automatically.”

4. On the "IP Address" tab of the "TCP/IP Properties" sheet, click the bullet in front of "Specify an IP address". On-campus subscribers enter the IP address for your machine (128.211.___.___ from the information that your main office supplied you) and the subnet mask (255.255.255.0).

Off-campus subscribers use the IP address supplied to them via e-mail and 255.255.255.240 for their Subnet mask.



5. Click the "WINS Configuration" tab and click the bullet in front of "Enable WINS Resolution." Enter the IP address of the WINS server (128.210.10.43) in the "WINS server search order" box. Then click the Add button. Repeat this step so that the WINS server IP address is listed twice.

6. Click the "Gateway" tab. On-campus subscribers enter the gateway address for your subnet (128.211.____.1 from the supplied information) under "New gateway:" and click the "Add" button.

Off-campus subscribers use the Default Gateway that was supplied to them via e-mail (128.211.___.___).



7. Click the "DNS Configuration" tab. Click the bullet in front of "Enable DNS" and enter your machine's host name (__________ from the supplied information) and domain (resnet.purdue.edu). Enter the IP address of the name server (128.210.11.57) under "DNS Server Search Order" and click the "Add" button next to it. Enter the IP address of the secondary name server (128.210.11.5) in the same manner.

8. Enter "cc.purdue.edu" in the text box below "Domain Suffix Search Order" and click the "Add" button next to it. Then enter "purdue.edu" in the same text box and click "Add " again.

9. Click the "Bindings" tab. Make sure that "Client for Microsoft Networks" is present and has a check mark in front of it. If there is no check mark, click on the box. If it is not present, see "Troubleshooting" below.

10. Go back to the "IP Address" tab and double-check your IP address entry. It is very important that you get this entry correct! Be certain that you have not accidentally entered your gateway address in this box!

11. Click on the "OK" button. The "Network" sheet should now be visible again.

12. If you want to share files and/or printers with other ResNet subscribers, access your career account files, or print to the residence hall printer from within a Microsoft Windows application, then look for "File and printer sharing for Microsoft Networks" in the list of network components. If this component is missing, then click on the "Add" button. In the "Select Network Component Type" window, select "Service" and click on the Add button. In the "Select Network Service" window, select "Microsoft" on the left-hand side and "File and printer sharing for Microsoft Networks" on the right-hand side, then click on the OK button. Click on the CANCEL button in the "Select Network Component Type" window. If it is not already selected, choose "Client for Microsoft Networks" as your Primary Windows Logon from the drop down list.



WARNING! Enabling Microsoft file and printer sharing can expose your machine to malicious attacks from other network users. Only share files with the Access Type set to "Read-Only" unless it is absolutely necessary to grant someone "Full" access and ALWAYS set a password on shared folders.

13. Click on the "OK" button of the "Network" sheet.

14. At this point you will be prompted to restart your computer. Click on the "Yes" button and wait for your system to reboot. Once rebooted, your system should have a functional network connection. See “Using Your ResNet Connection” below.

Windows 2000

[The following instructions are specifically for the Windows 2000 operating system. If your machine is running Windows 95, 98, or Me, you should skip this section.]

1. Right-click (click using the right mouse button) on the "My Network Places" icon, then select "Properties" from the menu that is displayed.

Click the "Start " button on your task bar and select "Control Panel" from the "Settings" menu. Then, double-click on the "Network and Dial-up Connections" icon in the "Control Panel" window.



2. Double-click the “Local Area Connection” icon, then, click the “Properties” button.

3. Click on “Internet Protocol (TCP/IP)” to highlight it, then click the “Properties” button.

4. Click the radio button for “Use the following IP address:” On-campus subscribers enter

the IP address for your machine (128.211.___.___ from the information supplied to you), the Subnet mask (255.255.255.0), and the Default Gateway (128.211.___.1).

Off-campus subscribers use the IP address supplied to them via e-mail, 255.255.255.240 for their Subnet mask and the Default Gateway that was supplied to them via e-mail (128.211.___.___).

5. Click the radio button for “Use the following DNS server addresses:”; enter 128.210.11.57 for the “Preferred DNS server:”; then enter 128.210.11.5 in the “Alternate DNS server:” box.



6. Click the “Advanced” button and then click on the “WINS” tab. Click the “Add” button and enter 128.210.10.43 in the “WINS server:” text box. Click the “Add” button. Click the “OK” button.

7. Click on the “DNS” tab and uncheck the box at the bottom of the dialog box labeled “Register this connection’s address in DNS”. Then, click the “OK” button.


Purdue University ResNet Guide8. Click the “OK” button on the “Internet Protocol (TCP/IP) Properties”

dialog. Then click “OK” on the “Local Area Connection Properties” dialog. Close the “Network and Dial-up Connections” box.

9. Try your Ethernet connection. It should be fully functional at this point. If not, reboot your machine and then try your connection.

Troubleshooting

If you believe that you have correctly installed your network adapter and software drivers, but your network connection still does not function, verify that all of the installation steps were performed correctly. Check that the IP addresses for your host, the gateway, and the DNS servers were entered accurately. Correct any entry that is in error. (In some cases, you will have to delete the incorrect entry and enter it again correctly.) Once you are certain that everything is correct, reboot and try it again. If your system still refuses to function properly, see "Getting Help" below.

A few typical problems and their resolutions

Telephone cables DO NOT WORK as network cables. You must use a Category 5 (CAT 5) twisted pair cable. If you live on campus, jumper cables that are the correct type for your ResNet connection may be purchased at the main office of your residence. Off-campus residents will need to purchase jumper cables from one of the many local vendors that carry them. Ask for a “UTP Category 5 data cable”. They are available in various lengths.

If your "Client for Microsoft Networks" entry is missing: Click on the Add button in the "Configuration" tab of the "Network" window. In the "Select Network Component Type" window, select "Client" and click on the Add button. In the "Select Network Client" window, select "Microsoft" on the left-hand side and "Client for Microsoft Networks" on the right-hand side, then click on the OK button. Click on the CANCEL button in the "Select Network Component Type" window, then click on OK in the "Network" window.

If your "TCP/IP" entry is missing: Click on the Add button in the "Configuration" tab of the "Network" window. In the "Select Network Component Type" window, select "Protocol" and click on the Add button. In the "Select Network Protocol" window, select "Microsoft" on the left-hand side and "TCP/IP" on the right-hand side, then click on the OK button. Click on the CANCEL button in the "Select Network Component Type" window, then click on OK in the "Network" window.

If your "File and printer sharing for Microsoft Networks" does not work: You MUST enter your login and password when prompted during Windows startup. Do not click on CANCEL, otherwise "File and printer sharing for Microsoft Networks" will be disabled.



4. Installation Guidelines for Macintosh Personal Computers

The best sources of detailed instructions for installing your equipment are the manuals that were packaged with the equipment. It is beyond the scope of this guide and simply not practical to try and provide detailed instructions for installation of the network adapter and associated software drivers. Therefore, the following should be treated as general guidelines for the process of getting your machine operational as a client of the Purdue Data Network.

Hardware Installation

Many recent Macintosh machines have onboard Ethernet. There is no need to install a NIC inside these machines. However, you may need to attach an adapter to make your "EtherTalk" interface compatible with the industry standard 10base-T network connection in your room. Consult your owner's manual to determine whether an adapter is required. If you do not have an onboard Ethernet, read the manual that is provided with the network adapter that you purchase and follow the directions given to install it in your machine. University personnel, including your RCCs, are not authorized to perform hardware installations in student owned computers. Therefore, if you need help with hardware installation, you will need to ask your computer vendor, an authorized service center, a family member, or friend to help you install your network adapter.

Subscribers that reside in locations where Ethernet is not available should refer to the section entitled “ResNet 1-Meg Modem (on-campus xDSL)” or “Verizon ADSL (off-campus)” in this document for cabling instructions.

Connect the twisted-pair jumper cable between the network connector (or adapter) on your machine and the ResNet outlet, on the wall of your room, which was assigned to you. If you are the first subscriber in your room, your outlet will typically be the one labeled with "-A" appended to the room number. If your roommate is also a ResNet subscriber, then both the "-A" and "-B" outlets will be active. In this case, even though either outlet will work, you should still use the outlet that was assigned to you in order to avoid future complications. Do not attempt to use the "-1" or "-2" outlets. They are only used for telephone connections and do not work as data connections. In fact, use of these outlets could damage your Ethernet interface.

Software Installation


Purdue University ResNet GuideIf you installed a NIC in your machine, you may have to install drivers for it as well. Follow the installation instructions provided with the adapter to do this. Machines with onboard Ethernet will already have drivers installed.

You must tell your system where it can be found on the network (IP address). You also need to provide some other necessary information that is shown here as well as provided to you by the main office of your residence. The following directions assume that you have MacOS System 7.5.3 or later.

1. Open your main menu by clicking on the apple in the upper left corner of your screen. Keeping the mouse button depressed, drag the cursor down to "Control Panels" on the menu. This will open a sub-menu. Continue to drag the cursor down to "AppleTalk" on the sub-menu and release the button.

2. On the AppleTalk window, select "Ethernet" from the drop down list beside "Connect via:" (Only one entry from the list is visible until you click on the text box.) Then close the window by clicking on the button in the upper left corner of the window.

3. Once again, click on the apple and drag down to "Control Panels" on the main menu, then to "TCP/IP" on the sub-menu and release the button. Under "Connect via:" select "Ethernet" from the drop down list. Then select "Manually" from the drop down list next to "Configure:"

4. Enter the IP address for your machine (128.211.___.___ from the information supplied to you by your residence or, if you live off campus, the information that was e-mailed to you) in the text box next to "IP address:"


Purdue University ResNet Guide5. On-campus subscribers enter 255.255.255.0 (off-campus subscribers enter

255.255.255.240) in the text box next to "Subnet mask:"

6. Enter the gateway address (128.211.____.1 from the information supplied to you or, if you live off campus, 128.211.___.___ from the information that was e-mailed to you) in the text box next to "Router Address:"

7. Enter the name server's IP address (128.210.11.57) in the text box next to "Name server addr.:" Then enter the IP address for the secondary name server (128.210.11.5) under the name server's address in the same text box.

8. Enter "cc.purdue.edu" (without the quotes) in the text box under "Search domains".

9. Go back and double-check your IP address entry. It is very important that you get this entry correct! Be certain that you have not accidentally entered the gateway address in this location!

10. Close the window by clicking the button in the upper left corner of the window. You are now ready to test out your network connection.

Troubleshooting

If you believe that you have correctly installed your network adapter and drivers (if necessary), but your network connection still does not function, verify that all of the installation steps were performed correctly. Check that the IP addresses for your host, the gateway, and the name servers were entered accurately. Make corrections to any entry that is in error. Once you are certain that everything is correct, try it again. If your system still refuses to function properly, see "Getting Help" below.

5. ResNet 1-Meg Modem (on-campus xDSL)

For residence halls and apartments where Ethernet is not available, the ResNet service is provided by use of the Nortel 1-Meg Modem. This modem uses a new digital subscriber line (xDSL) technology that allows data rates that are many times faster than normal dial-up modems (currently approximately 960 kb/s down-link and 120 kb/s up-link). Although the modem's data rate is slower than that of an Ethernet connection, the difference in speed will not normally be noticeable for most network activities such as viewing web pages with a web browser, reading e-mail or logging into a remote server using telnet. Unlike a dial-up modem, the network link provided by this modem is available 24 hours per day. The telephone can be used normally while you are


Purdue University ResNet Guideon-line with your computer - data and voice communications are transmitted simultaneously on the same wire.

Set-up procedures for your computer (described in this Guide) are the same for a xDSL connection as they are for an Ethernet connection, with one minor exception. The 10Base-T twisted-pair data cable from your computer's network interface card (NIC) plugs into the data connector on the 1-Meg Modem rather than the ResNet wall outlet. Set-up procedures for the 1-Meg Modem are described below.

1. Connect your computer to the modem. Both ends of your 10Base-T data cable have RJ-45 connectors (8 contacts). One end should be plugged into the connector on your computer's NIC. The other end plugs into the data connector on the modem (far right connector when looking at the back of the modem).


Purdue University ResNet Guide2. Unplug your telephone from the wall jack. The telephone cable has RJ-

11 connectors (6 contact positions, some only have 2 or 4 contacts inserted) at both ends. One end should still be connected to your telephone. Plug the other end into the telephone connector on the modem (second from the left when looking at the back of the modem).

3. Connect the modem to your wall jack. Plug one end of the supplied telephone cable (RJ-11 at both ends) into the line connector on your modem (far left connector when looking at the back of the modem). Plug the other end into the telephone wall jack in your room.

4. Connect the power adapter. Plug the cable that is attached to the power cube into the 16V AC connector on the modem (second from right when looking at the back of the modem). Plug the power cube into a power outlet in your room.

5. Turn the modem power switch on. Depress the rocker switch on the side that has the icon showing a "1" inside the circle. At this point, the Power and Loop Status indicator lights should be GREEN. If not, see "Getting Help" in this Guide. The modem is now ready for use.

If, during use, your ResNet connection stops working for no apparent reason, it is possible that your 1-Meg Modem has locked up. Disconnect the power cable from the modem for approximately 30 seconds, then plug it back in to reset the electronics in the modem. If this does not fix the problem, see “Getting Help” below.

6. Verizon ADSL modem (off-campus)

Off-campus faculty, staff, and students that subscribe to Verizon’s ADSL service with Purdue as their Internet Service Provider (ISP) install their network interface card (NIC) and configure their software as described previously in this guide. But, they must connect their computer’s NIC to the 10BaseT Ethernet connection on the ADSL modem, purchased from Verizon, as described below. The instructions given here are only guidelines, your modem may be different from the one illustrated here. Please refer to the instructions packaged with the modem if you have questions.

1. Connect one end of the Ethernet crossover cable to the “DATA” connector on the modem. Connect the other end of the Ethernet crossover cable to the network card in your computer. The “DATA” connection is located on the back panel of the ADSL Modem. The Ethernet crossover cable is included in the ADSL Modem package.

2. Connect the RJ-45 end of the ADSL cable to the RJ-45 jack on the wall plate. Connect the RJ-11 end of the ADSL cable to the “LINE” connector on the modem. The “LINE” connection is located on the back panel of the DSL Modem. The ADSL cable is included in the ADSL modem package. (RJ-45 and RJ-11 connectors look like those on your telephone. The RJ-45 end will be wider than the RJ-11. Also, some installations use a standard telephone wall plate. In those cases, a standard telephone cable, with RJ-11 connectors at both ends, is used as the ADSL cable.)

3. Connect the modem’s power pack cable to the power connector on the rear panel of the modem and plug the power pack into an available outlet.



ADSL Modem Indicator Lights

connected and communicating with GTE and is operating at full speed. If the “Data” light is blinking, there may be a problem your connection.

When your system is hooked up correctly, all three indicator lights should be on. You can double-check your connection by launching a web browser and going to the Purdue University home page (http://www.purdue.edu).


Purdue University ResNet Guide7. Multiple Connections

[This section applies specifically to the use of mini-hubs and routers on campus. A router or hub can be purchased for use in off-campus locations to connect more than one machine to the ADSL modem. The hub or router that you purchase may not be the same as one of those described below, but the wiring configuration should be very similar. You will have to refer to instructions packaged with the device for details

Each machine connected to the network must have its own unique IP address. Since Purdue issues only one IP address per eligible person for use with off-campus ADSL, one individual cannot use a hub to connect more than one machine. Instead, he/she must use Network Address Translation (typically via a router) to connect more than one machine.

Hubs cannot be used to connect multiple machines to Ethernet ports in the residence halls.]

Since a 1-Meg Modem only has one network connector, an additional piece of equipment is necessary to share that connection between two or more computers. In most locations, where there are only two residents per room or apartment, a mini hub is used to provide the additional connection. The 1-Meg Modem has a design limitation allowing only two network connections. It is necessary to use Network Address Translation (NAT) in locations where there are three or more residents. Therefore, the Linksys Etherfast Cable/DSL Router is used to provide the additional connections. Please refer to the set-up instructions (below) for the device that your residence provided you.

Mini Hubs

The 1-Meg Modem is capable of supporting two subscribers. If both occupants of a room that is serviced by xDSL subscribe to ResNet, the second subscriber will be issued a mini hub instead of a 1-Meg Modem. Instructions for connecting the mini hub are given below. Please note that both subscribers will


Purdue University ResNet Guideneed to connect their PC's NIC to the mini hub – only the mini hub connects to the 1-Meg Modem.

On the back of the mini hub is a power connector (far right), four RJ-45 data connectors, and a slide switch. While referring to the diagram below, perform the following steps to connect your mini hub.

1. Insure that the slide switch is set to the "MDI [to HUB]" position (toward the outside of the box). Your ResNet connection will not work if this switch is in the wrong position.

2. Connect the data connector labeled "4" (far left connector) to the RJ-45 data connector on the 1-Meg Modem (far right connector) using a 10Base-T jumper cable. If your roommate's computer is already connected to the RJ-45 data connector on the 1-Meg Modem, then it will have to be disconnected first.

3. Connect the network interface card (NIC) of each PC to the RJ-45 data connector labeled "1" or "2" on the mini hub using 10Base-T jumper cables.

4. Connect the power cube cable to the power connector (far right) on the mini hub and plug the power cube into a power outlet in your room. The mini hub does not have a power switch. Therefore, the hub is "ON" as long as the power cube is plugged into power.



Assuming that all of the connections have been made correctly and that the power is ON to all of the equipment, the Ethernet Link Status LED on the 1-Meg Modem should now be green. Also, the mini hub LEDs labeled "1", "2", "4", and "POWER" should all be on. The LEDs labeled "1", "2", "3", and "4" are link status indicators which are equivalent to the Ethernet Link Status LED on the 1-Meg Modem. If your LEDs indicate different states than the ones described here, you should go back and double-check all of your connections.

The remaining two LEDs on the front of the mini hub are labeled "ACTIVITY" and "COLLISION". The activity LED will flash each time an inbound or outbound data packet is detected by the hub. The collision LED lights when two PCs try to transmit at the same time and the data packets "collide" on the Ethernet. This is a normal condition that occurs occasionally on Ethernet networks. But, if this LED stays on continuously, there is a problem - see "Getting Help" above.


Purdue University ResNet GuideThe Linksys Etherfast Cable/DSL Router

In locations where there are three or more residents in a room or apartment, the Linksys Etherfast Cable/DSL Router is used to provide multiple connections to the network through the 1-Meg Modem. Due to the fact that the router uses Network Address Translation (NAT), there is only one public IP address associated with the connection. Subscribers in these locations are issued private IP addresses that begin with “192.168”. These addresses are only usable on the private network that is created within your room or apartment by the four-port switch that is built into the Linksys Etherfast Cable/DSL Router. Therefore, even the first subscriber in a room or apartment must use the router along with the 1-Meg Modem in order to establish a usable connection.

In addition to providing multiple connections, the Linksys Etherfast Cable/DSL Router also acts as a firewall between the private network in your room or apartment and the public network. This feature provides additional security, but as a result, has some limitations as well. The most notable limitation is that you will not be able to use Microsoft File and Printer Sharing between your computer and your neighbor’s computer (other than your roommates’ machines on your private network). Also, since your computer does not have a public IP address, it is not possible to run a public server (FTP, HTTP, etc.) on your machine and have it accessible from the Internet. The router provides for one exception to this rule: ONE machine can be set up to use IP address 192.168.xxx.200 (where xxx is the subnet number of your private network – usually your building number) which is called the DMZ address. The router forwards all TCP/IP ports from the public IP address to the DMZ address.

[It is not possible to disable the firewall function of the router due to the nature of NAT.]

The 10/100 four-port switch built into the router is capable of port-to-port speeds of 100 Megabits per second. So, file transfers and games played


Purdue University ResNet Guidebetween your machine and your roommates’ machines will be lightning fast if you are using 10/100 NICs in your machines. Data transfers to/from the public network will remain at speeds dictated by the 1-Meg Modem and/or the Internet route that is used.

On the back of the router are a power connector (far right) and six RJ-45 data connectors. While referring to the diagram below, perform the following steps to connect your router.

1. Connect the data connector labeled "WAN" (far left connector) to the RJ-45 data connector on the 1-Meg Modem (far right connector) using a 10Base-T jumper cable.

2. Connect the network interface card (NIC) of each PC to an RJ-45 data connector labeled "1", "2", “3”, or “4” on the router using 10Base-T jumper cables. [Do not use the “Uplink” connector.]

3. Connect the power cable (with power module attached) to the power connector (far right) on the router, connect the power cord to the power module and plug the power cord into an outlet in your room. The router does not have a power switch. Therefore, it is "ON" as long as the power cable is plugged into power.

Assuming that all of the connections have been made correctly and that the power is ON to all of the equipment, the Ethernet Link Status LED on the 1-Meg Modem and the Link LED on the router should now be green. Also, on the router, the Link/Act LEDs labeled "1", "2", “3”, or "4" that correspond to the computers that are connected should all be on. If your LEDs indicate different states than the ones described here, you should go back and double-check all of your connections.



The Linksys Etherfast Cable/DSL Router provides DHCP service to the private network within your room or apartment. Therefore, you have two options for setting up your TCP/IP parameters on your computer. You can follow the directions given in the “Installation Guidelines …” sections above to enter the parameters that were given to you by the main office of your residence or you can set your machine to obtain the IP address automatically from the router via DHCP.



LAN Indicator lights

Power Green when the router is receiving power.

Link/Act If the LED is continuously illuminated (green), the router is successfully connected to a computer through the corresponding port (1, 2, 3, or 4). If the LED is flickering, the router is actively sending or receiving data over that port.

Full/Col If this LED is continuously illuminated (green), the connection made through the corresponding port is running in Full Duplex mode. If the LED is flickering, the corresponding connection is experiencing collisions. Infrequent collisions are normal. Too many may be an indication of a problem.

100 or 10/100 The 100 LED illuminates (orange) when a successful 100 Mbps connection is made through the corresponding port.

WAN Indicator lights

Link The Link LED illuminates (green) when a successful connection is made between the router and the 1-Meg Modem.

Act The Act LED flickers (green) when the router is sending or receiving data via the WAN port.

Diag The Diag LED illuminates (red) when the router goes through its self-diagnosis mode during boot-up. It will turn off upon successful completion of the diagnostics. If this LED stays on for an abnormally long period of time, you should seek help from the PDN staff (see “Getting Help” above).

If you think that the router is hung up or not operating normally, you may try pressing the Reset button on the front of the router momentarily to clear the condition. DO NOT hold the Reset button in for an extended period of time. This could cause the router to lose all of its settings (including its IP address) and revert to factory defaults. A PDN staff member would then have to reconfigure the router for you.



8. Using Your ResNet Connection

Regulations and Policies

Your use of the ResNet connection is subject to local, state, and federal laws as well as Purdue University policies. Please refer to “Program Responsibilities” for details.

Networking Software

There are a few programs that most people find useful when taking advantage of their network connection. Two popular tools for TCP/IP networking are telnet and ftp. Many versions of these programs can be found on Internet web servers and FTP sites. Microsoft Windows includes basic versions of both of these programs that can usually be found in the "\WINDOWS" folder. The other tool that most people find useful is a web browser. The two most popular web browsers are Netscape Navigator and Internet Explorer from Netscape and Microsoft respectively. These programs are readily available in most computer outlets or they can be downloaded from their web sites. Links to these sites are included in the list of web sites below.

The Internet is very much like a large city - a very large city! It provides literally millions of big-city-like resources such as banking, communications, shopping, and education – not to mention fun and games. Unfortunately, it also has the criminal element. There are thousands of people using the Internet with one purpose: to take advantage of unprepared PC owners. The security of your computer is your responsibility. There are no firewalls or other security measures between your computer and the rest of the world when you connect it to the ResNet at Purdue. All ResNet subscribers should have a virus scanner running on their PC and should consider installing “firewall” software. There are free versions of both available to ResNet subscribers. Follow the security related links on our web site for more information.

A few Web Sites

A short list of web sites, to help you begin exploring the World Wide Web on the Internet, can be found at http://www.purdue.edu/resnet/Links.html. If you do not have a web browser installed on your PC, you will have to install one in order to follow the links in this list. Web browsers are typically several megabytes in size; therefore it will be helpful to use either a CD-ROM or Zip disk to install your browser. It is also possible to download a browser from an FTP site on the Internet. Obviously, you will not be able to access any of these sites from your own machine until you have your ResNet connection installed and operating.



9. Getting Help

If you encounter problems while installing your network adapter or setting up your machine for use with your ResNet service, there are several ways for you to seek help. Often, the fastest, easiest way to get help is to ask a friend or roommate, which has already succeeded with his or her own machine, to help you with yours. He/she may be able to spot something that you have overlooked. Also, if you have Internet access, you may find answers to your questions on Purdue's ResNet home page: http://www.purdue.edu/resnet .

Subscribers that live on campus may contact your Resident Computer Consultant (RCC). This is a student that lives in your residence and is employed by the Computing Center to provide you help with your ResNet connection. If you don't already know this person, you may obtain the name of your RCC from the main office of your residence or from the ResNet home page listed above.

There are several other ways to obtain help with your ResNet connection. You may call the ResNet help line at 49-67500 or the PUCC Information Center at 49-49944. These numbers are not staffed 24 hours per day. Please check the Information Center’s Web page, http://labinfo.cc.purdue.edu, for current hours of operation. You may also fill in the Help Request Form on the ResNet home page or e-mail to [email protected]. Depending upon the nature of your problem, the appropriate personnel will be notified and they will contact you to set up an appointment during which they will attempt to resolve your problem.

Other possible sources of help for machine configurations, though not specific to Purdue University, are the ResNet web pages for other universities. These may also be a source of other interesting networking information. A list of ResNet web pages can be found at http://rescomp.stanford.edu/directory/others.html .
