Installation Manual Quidway S3900 Series Ethernet Switches Chapter 2 Preparation


2-1

Chapter 2 Preparation

2.1 Safety Precautions

To avoid any device impairment and bodily injury caused by improper use, observe these rules:

Before cleaning the switch, unplug the power plug of the switch first. Do not clean the switch with wet cloth or liquid.

Do not place the switch near water or any damp area. Prevent water or moisture from entering the switch chassis.

Do not place the switch on an unstable case or desk. The switch might be damaged severely in case of a fall.

Ensure proper ventilation of the equipment room and keep the ventilation vents of the switch free of obstruction.

Make sure that the operating voltage is the same one labeled on the switch. Do not open the chassis while the switch is operating or when electrical hazards

are present to avoid electrical shocks. When replacing interface cards, wear ESD-protective gloves to avoid damaging

the cards.

2.2 Installation Site

The S3900 series must be used indoors. You can mount your switch in a cabinet or on a desk, but make sure:

Adequate clearance is reserved at the air inlet/exhaust vents for ventilation. The cabinet or desk has a good ventilation system. The cabinet is sturdy enough to support the device and its accessories. The cabinet or desk is well earthed.

To ensure normal operation and long service life of your VG, install it in an environment that meets the requirements described in the following subsections.

2.2.1 Temperature/Humidity

You must maintain a proper temperature and humidity in the equipment room. Long-term high humidity may lead to bad insulation, electricity leakage, mechanical property changes, and corrosion. However, if the relative humidity is two low, captive screws may become loose as the result of contraction of insulation washers and static electricity may be produced in a dry environment to jeopardize the CMOS circuits on the device. High temperature is the most undesirable condition, because it accelerates



2-2

aging of insulation materials and can thus significantly lower reliability and service life of your switch.

For the temperature and humidity requirements of different models, refer to section 1.11 “Features of the S3900 Series”.

2.2.2 Cleanness

Dust is a hazard to the operating safety of your device. The dust accumulated on the chassis can be adsorbed by static electricity and result in poor contact of metal connectors or metal contact points. This can not only shorten the service life of your device but also cause communications failures. When the relative indoor humidity is low, electrostatic adsorption is more likely to happen. The contents of the dust must be limited as shown in Table 2-1:

Table 2-1 Dust content limits in an equipment room

Substance Unit Content

Dust Particles/m³ ≤ 3 × 104

(No visible dust on the tabletop for three days)

Remark: the diameter of a dust particle ≥ 5 μm

Besides dust, there are rigorous limits on the harmful gases that can accelerate the erosion and aging of metals, such as salts, acids, and sulfides, as shown in Table 2-2.

Table 2-2 Harmful gas limits in the equipment room

Gas Maximum (mg/m3)

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

2.2.3 Electromagnetic Susceptibility

The operation of your switch can be affected by external interferences, such as conducted emission by capacitance coupling, inductance coupling, electromagnetic wave radiation, and common impedance (including the grounding system) coupling, and leads (power cords, signaling cables and output wires. To eliminate the interferences, make sure to:



2-3

For the AC power supply that adopts TN system, use a single-phase three-line power socket with Protection Earth (PE) to effectively filter interference from the power grid.

Keep the device far from radio transmitting stations, radar stations, and high-frequency devices.

Use electromagnetic shielding when necessary, for example, use shielded interface cables.

Route interface cables only indoors to prevent signal ports from getting damaged by over-voltage or over-current caused by lightning strikes.

2.2.4 Laser Safety

The S3900 series are class-1 laser devices.

If the extended optical boards on your switch are operating, do not stare into the optical ports because the laser light emitted by the optical fiber can hurt your retina.

Caution:

Staring into the laser beam produced by the fiber can hurt your eyes.

2.3 Installation Tools

Flat-blade screwdriver Phillips screwdriver ESD-preventive wrist strap

Caution:

The installation tools are not provided with the S3900 series.

Chapter 3 Installation

Caution:

When you ask your sales agent to maintain the switch, you must ensure that the dismantlement-preventive seal on a mounting screw of the switch chassis is intact. If you want to open the chassis, you should contact the agent for permission. Otherwise, you will bear any consequence resulted from your actions without permission.

3.1 Mounting the Switch

3.1.1 Mounting the Switch into a 19-Inch Standard Cabinet

You can install the S3900 series into a 19-inch standard cabinet in one of the following ways:

Use front mounting ears Use front mounting ears and a tray Use front mounting ears and rear mounting ears

The installation methods depend on the width and depth of the switch. For the specific installation methods, see Table 3-1.

3.1.2 Mounting the Switch on a Desk

When placing the switch on a desk, you simply need to:

Make sure that the desk is clean, flat, and sturdy. Allow 10 cm (3.9 in.) of clearance around the sides of the chassis. Do not place heavy objects on the switch.

3.2 Connecting the Power Cord and the Ground Wire

3.2.1 Connecting the AC-Input Power Cord

I. AC-input power socket (recommended)

You are recommended to use a single-phase three-line power socket with a ground contact or a general purpose PC power socket, making sure that the power point is well connected to building ground. Normally, the ground point of the power source in a building was buried in the ground during the construction and wiring. Still, you must make sure of that.



3-8

Figure 3-10 Power socket (recommended)

II. Connecting the AC-input power cord

Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear of the chassis and the other end to the ground as near as possible.

Step 2: Connect one end of the power cord to the power socket on the rear of the chassis, and plug the other end to the AC power jack of the power source.

Step 3: Check that the PWR LED on the front panel of the switch is ON.

Caution:

Before powering on the switch, connect the ground wire.

Step 4: Check that the RPS LED on the front panel of the switch is ON.



3-10

Caution:

Before powering on the switch, connect the ground wire. The length of the DC power cord must be less than 3 m (9.8 ft.). Only the PoE power supply recommended by Huawei can be used for the

S3928P-PWR-SI, S3928P-PWR-EI, and S3952P-PWR-EI. The –48 VDC from the equipment room cannot be used directly. Otherwise, devices may be damaged.

3.2.3 Connecting the Ground Wire

Caution:

Correctly connecting the switch ground wire is crucial to the lightning protection and electromagnetic susceptibility (EMS) of a switch.

The power input end of the switch is connected with a noise filter, whose central ground is directly connected to the chassis, forming the chassis ground (commonly known as PGND). This chassis ground must be securely connected to the earth ground so that the faradism and leakage electricity can be safely released to the ground, enhancing the EMS capability of the switch.

Ground your switch as follows:

When a grounding strip is available at the installation site, attach one end of the yellow/green ground wire of the switch to the grounding screw on the grounding strip and fasten the captive nut. (Note that the fire main and lightning rod of a building are not suitable for grounding the switch. The ground wire of the switch should be connected to the grounding device for the equipment room.)

3.3 Connecting Optical Fiber

Caution:

After a switch starts, the PON interface may emit invisible radial when there is no optical connector connected to it and the protective cap is removed from it. Therefore, do not stare into the optical interface.

Be sure to cover the protective cap within 10 seconds if an optical connector is not in use to keep the optical connector clean.

Be sure to cover the protective cap if a PON interface has no optical connector attached.

Place the protective caps in a safe place when a PON interface has fiber connected to prepare for the cases the fiber is pulled out.

3.4 Connecting the Switch to a Console Terminal

3.4.1 Console Cable

Console cable is an 8-core cable. At one end of the cable is a crimped RJ-45 connector to the Console port of the switch, and at the other end of the cable is a DB-9 (female) connector to the serial port on the console terminal. See Figure 3-18.

3.4.2 Connecting the Console Cable

Follow these steps to connect a terminal device, a PC for example, to the switch:

Step 1: Plug the DB-9 (female) connector of the Console cable to the serial port of the PC where the switch is to be configured.

Step 2: Connect the RJ-45 connector of the console cable to the Console port of the switch.

Caution:

Read the mark for the port to be connected carefully to make sure it is the right port.

Note:

The serial ports on PCs do not support hot swapping. Therefore, do not insert or remove a serial interface cable from a PC that is connected to a switch with power. In connecting a PC to the switch, first connect the DB-9 connector of the console cable to the PC and then the RJ-45 connector to the switch. In disconnecting them, remove the RJ-45 connector prior to the DB-9 connector.

Installation Manual Quidway S3900 Series Ethernet Switches Chapter 5 Loading Boot ROM and Host Software


5-1

Chapter 5 Loading Boot ROM and Host Software

Switch software loading through serial ports in the past is time consuming and cannot be operated remotely. To address these problems, TFTP and FTP are used to allow software and file downloading through Ethernet ports. The following subsections describe how to load software and files in these two approaches.

5.1 Introduction to Loading Approaches

To load software remotely, use FTP or TFTP.

To load software at the local, use XModem at the Console port or TFTP/FTP at an Ethernet port.

Note:

Ensure that the Boot ROM and host software versions that you download can work with each other.

5.2 File attribute in Boot ROM

5.2.1 Introduction to File Attribute

In Boot ROM, application files, configuration files, and Web files support three kinds of attributes: main, backup, and none, which are described in Table 5-1.

Table 5-1 File Attribute

Attribute Usage Feature Identification

main Indicates the main boot file, which is used by a device to boot.

Only one application file, one configuration file, and one Web file in the Flash can have the main attribute.

(*)

backup

Indicates a boot file with the backup attribute. When a device cannot boot with the main boot file, it will use the backup boot file to boot.

Only one application file, one configuration file, and one Web file in the Flash can have the backup attribute.

(b)



5-2

Attribute Usage Feature Identification

none

Indicates a file having neither the main attribute nor the backup attribute.

— No special identification

Note:

The suffixes of application, configuration, and Web files are app, cfg, and web respectively.

A file can have both the main attribute and the backup attribute. Such a file is displayed with identification of (*b).

If you specify a file to have the main attribute when there is already a main boot file, the original main boot file will lose the main attribute, ensuring that only one application file, one configuration file, and one web file in the Flash have the main attribute. The same is true for the backup attribute.

Operations of a file are separate from those of the attributes. For example, when you delete a main boot file from the Flash, the main attribute of the file remains. If you download a valid file with the same name to the Flash, the new file will have the main attribute.

The file attribute feature is backward compatible. When you upgrade the Boot ROM of a device, the original default app boot file has the main attribute.

5.2.2 Impact of File Attributes on Downloading and Booting

I. Downloading

When you download an application, configuration, or Web file from the boot menu through TFTP or FTP, the device identifies the file by its suffix and checks the validity of the file if it is an app file. Then, the device displays a message for you to confirm if you want to set it as a boot file. You can set file attributes at prompt.

Note:

If a downloaded file has the same name as that of an existing file in the Flash, the new file will overwrite the original one, while having the same attributes.



5-3

II. Booting

When a device boots, it first uses the application file with the main attribute. If the boot operation fails, the device selects the application file with the backup attribute to try again. If the boot operation fails again, the device displays an error message and repeats the above procedure.

Note:

If the device boots failed with an application file with main attribute, it will display an alert message.

If the specified application file does not exist, the switch will automatically choose an existing valid application file to boot.

5.2.3 Setting the Attribute of a File

You can set the attribute of a file from the Boot menu.

The following takes an application file for example to describe the required steps:

I. Enter the Boot menu and input 2 to select “2. Select application file to boot” and enter the corresponding submenu.










0. Reboot

Enter your choice(0-9):2

Select application file to boot

1. set application files

2. set configuration files

3. set web files

0. return


II. Set the attributes of application, configuration, or Web files as needed. In this example, enter 1 to select “1. set application files”.

Please input the file number to change:

III. Set the attribute of file 2 to main.

Please input the file number to change: 2

Please input the file attribute to change (main/backup): main

The attribute of s3900-1.app is changed from main to none!!

When setting the attribute of a file, you can use the strings listed in the following table. The strings are case-insensitive.

Table 5-2 String to Input for the Attribute

Attribute String to input

main m, ma, mai, or main

backup b, ba, bac, back, backu, or backup

If a file has neither the main attribute nor the backup attribute after you change the attributes of other files, the device will give the file the attribute of none and display an alert message.

IV. If you change the attribute of an application file to main, the device will display a message for you to confirm whether you want to boot the device immediately.

Do you want to run s3900-2.app now? Yes or No(Y/N) y

If you enter y, the device will reboot immediately. If you enter n, the device will return to the [Select application file to boot] submenu.

5.3 Loading Software Locally

If your terminal is directly connected to the switch, you can load Boot ROM and host software locally. But before that, make sure they are correctly connected.



5-5

Note:

The steps that you should take to load Boot ROM program and host software are the same, except that during Boot ROM program loading you need to press <Ctrl +U> after accessing the Boot ROM menu and will view different prompt information. Boot ROM loading procedures are described below for example.

5.3.2 Loading Software from Console Port Using XModem

I. Introduction to XModem

XModem is a file transfer protocol widely used for its simplicity and good performance. XModem transfers files through the Console port, supporting data packets of 128 bytes and 1 KB. With respect to reliability, it supports checksum, CRC, and the error packet retransmission mechanism. Normally, the maximum number of retransmission attempts is ten.

XModem transfer is completed by receiving and sending programs together. Receiving program initiates packet checking method negotiation by sending the negotiation character. If negotiation passes, the sending program starts packet transfer. Upon receipt of a complete packet, the receiving program checks it using the agreed-upon check method. If the check succeeds, the receiving program sends an acknowledgement character; if the check fails, it sends a reject character. Upon receipt of the acknowledgement, the sending program continues to send the next packet; upon receipt of the reject, it retransmits the packet.

II. Loading BootROM

Follow these steps to download the Boot ROM program:

Step 1: Enter <6> or <Ctrl + U> in the Boot Menu to access the Boot ROM loading menu shown below:

Step 3: Load the host software.

<Quidway> boot boot-loader SWITCH.app

<Quidway> display boot-loader

The app to boot at the next time is: flash:/SWITCH.app

<Quidway> reboot

Note:

Power disconnection must be prevented during the loading process. The configurations that you just make cannot survive a reboot. Make sure you have

saved them before you have the system reboot. To validate the downloaded Boot ROM and host software, you must reboot the

switch. In case of inadequate Flash memory space, you can delete some of the program

files in Flash, those that are no longer in use for example, after completing Boot ROM loading. Then FTP the host program to the switch.

5.4.2 Loading Software Remotely Using TFTP

TFTP is similar to FTP in remote software downloading. But with TFTP, the switch can only be used as the client to download software to its Flash Memory from the TFTP server. After that, the remaining steps are the same as remote loading using FTP.

Chapter 6 Maintenance and Troubleshooting

6.1 Dealing with Loading Failures

If software loading fails, the system operates with the original version.

To address the failure cause, take these steps:

1) Check that the physical ports are correctly and securely connected. If they are not, reconnect them correctly and restart loading.

2) Check information about the loading procedures for input errors on the HyperTerminal.

If XModem is used, check that you have reset the baud rate of the HyperTerminal to 9600 bps after loading the software with another baud rate.

If TFTP is used, check that you have correctly specified the TFTP parameters: server and switch IP addresses; name of the software to be loaded; and path for the TFTP server to operate on program files.

If FTP is used, check that you have correctly specified the FTP parameters: server and switch IP addresses; name of the software to be loaded; and username and password.

3) Contact your sales agent for help if you cannot address the problem after taking the preceding two steps.

6.2 Dealing with Password Loss

6.2.1 Dealing with User Password Loss

You can set a password for the access to the switch via the Console port to prevent unauthorized access.

If you lost your user password, enter the Boot Menu first:

6.2.2 Recovering the BootROM Password

Contact your sales agent for help.

6.3 Dealing with Power System Failures

You can know whether the power system has failed by reading the PWR LED on the front panel. If the power system is operating normally, the PWR LED is ON. If not, check that:

The switch power cord is correctly connected. The power source can work with the switch.

6.4 Dealing with Configuration System Failures

If the switch is operating normally after it is powered up, it displays the start-up information on the console terminal. If the configuration system has failed, it displays illegible characters or nothing at all.

I. No information on the terminal

Take these steps to address the problem:

1) Check that: The power system is operating normally. The console cable is connected correctly.

2) Check that the console cable is in good condition and the terminal (HyperTerminal for example) parameter settings are correct.

II. Illegible characters on the terminal

Make sure you have set on your terminal (HyperTerminal):

Baud rate = 9600

Data bit: 8

Parity check: none

Stop bit: 1

Flow control: none

Terminal emulation: VT100

Reconfigure the parameters if their values are different.

Appendix A Lightning Protection of the Switch

A.1 Installation of Lightning Arrester for AC Power (Socket Strip with Lightning Protection)

Caution:

Lightning arrester will not be shipped with the switch. You should purchase it by yourself if needed.

If an outdoor AC power cord should be directly led to the switch, please serially connect the lightning arrester for AC power (Socket Strip with Lightning Protection) before you plug AC power cord into the switch, thus to prevent the possible damage to the switch due to lightning strike. You can use cable clips and screws to fasten the lightning arrester for AC power on the cabinet, workbench or the wall of equipment room.

Caution:

Make sure that the arrester is well grounded before using the lightning arrester for power.

After inserting AC power cord plug of switch into the socket of lightning arrester, if the green LED is on and the red LED does not alarm, it means that the lightning arrester of power is running and the function of lightning protection has taken effect.

Pay adequate attention if the red LED is on. You should correctly locate the problem, whether it is caused because the ground wire of the arrester is not well grounded or because the live and zero wires are connected in reverse direction. You may check that in the following way. When the red LED is on, use a multimeter to examine polarity at the power socket of the arrester. If it is same to that of the power socket in the equipment room, it means that arrester is not well grounded. If it is adverse to that of the power socket in the equipment room, it means that the power socket of the arrester is set to the reverse polarity. In this case, you should open the power socket of arrester to correct polarity. After that, if the red LED still alarms, it means that the arrester is not well grounded yet.

A.2 Installation of Lightning Arrester for Network Port

Note:

Lightning arrester for network port is specially designed for the Ethernet port of 10/100M electrical interface (RJ-45 connector is adopted in this case).

Caution:

Lightning arrester for network port will not be provided along with the switch, and you should purchase it by yourself if needed.

�If an outdoor network cable should be led to the switch, please serially connect the lightning arrester for network port before you plug this cable into the interface on the switch, in case of the possibility that the switch may be damaged due to lightning strike.

II. Installation procedure

Step 1: Tear the protection paper at one side of the double faced adhesive tape apart from the tape, and stick the tape on the surface of the arrester. Tear the protection paper at another side apart from the tape, and stick the arrester onto the chassis of the switch. The arrester should be attached on the chassis as close to the grounding screw as possible.

Step 2: According to the distance to the grounding screw of the switch, cut the ground wire of the arrester, and securely tightening its ground wire to the grounding screw of the switch.

Step 3: Use the multimeter to measure whether the ground wire of the arrester contacts well with the grounding screw of chassis.

Step 4: According to the instruction of arrester for network port, connect the arrester with switch by the cables (be carefully with the cable direction. Outdoor network cable should be inserted into the arrester‘s IN end, and the cable connected to the switch should be inserted into the arrester’s OUT end). When you do that, observe whether the arrester indicators normally display.

Note:

The instruction of lightning arrester for network port contains the technical specifications, installation and maintenance guide of the arrester. Please carefully read it before installing the arrester.

Step 5: Use the nylon ties to bundle the cables neatly.

III. Installation precautions

Fully consider the following items in the installation process, otherwise, the performance of the lightning arrester for network port will be affected:

Lightning arrester for network port is installed in reverse direction. In practice, the “IN” end should be connected to the outdoor network cable and the “OUT” end to the network port on the switch.

Lightning arrester for the network port is not well grounded. The ground wire for the arrester should be as short as possible, so to ensure its good contact with the grounding screw of the switch. After the connection, use the multimeter to confirm that.

The lightning arrester for the network port is not installed completely. If the switch has more than one network ports to interconnect with other devices via cables outdoor, you should install lightning arresters for all these network ports for protection.
