1.5.2 Restore GMAC-5 factory settings If desired, you can clear GMAC-5’s entire current configuration at any time and return the settings to the factory default values. To do this:

• Press and hold the Act button on the front panel for at least 20 seconds, until all three status LEDs are on. Then release the button. The unit will restart with factory settings.

• This procedure also returns the system user name and password to their original default values of “admin” and “admin”.

1.5.3 Booting into bootloader mode Bootloader mode allows you to perform system software upgrades and also to upload a previously saved configuration.

In case you need to use the bootloader mode, use the “Switch to bootloader” button in the Configuration screen on the web interface (Figure 10).

Figure 3: Bootloader mode button

Another method for entering bootloader mode is to press and hold the Act button on the front panel, and then press the Reset button right next to it, or just plug the power in while holding the Act button.

In bootloader mode GMAC-5 receives its IP address from DHCP server. If no address is received, GMAC-5 uses the default IP address: 192.168.0.198.

When GMAC-5 is in bootloader mode and has received an IP address from DHCP, the green status LED (see Figure 1) blinks slowly. If the default IP address is being used (after a timeout), the yellow status LED will also be blinking. During file upload the LEDs will also blink; the rate at which they will blink depends on the file type.

Note: if you boot the device to bootloader mode (normally for performing updates or restoring user settings), but don't log into the web interface of the device for 5 minutes, the device automatically restarts in normal operation mode.

If the GMAC-5 unit always boots in to the bootloader, this means that the main software is corrupt. You will need to update the software file again.

2. INSTALLATION The initial configuration of the device is fully performed through the web interface, and therefore the installation begins with connecting it to the local network.

2.1 Physical setup 1. Connect an Ethernet cable to the RJ45 connector marked LAN on the front panel.

2. Connect input power to the plug on the rear of the unit.

2.2 Access the web interface setup 1. When switched on for the first time, GMAC-5 attempts to acquire an IP address automatically from

DHCP on the network. In the case that there is no DHCP server available in the network – for example, when you are connecting GMAC-5 directly to a computer – or in any other case of failure to set the IP address automatically, the device falls back to the default address of 192.168.0.198, subnet class C. This process can take up to one minute.

2. When configuring the GMAC-5 through a direct connection to a computer, the “network segment” (the first 3 nodes) of your computer’s IP address must match the network segment of G4’s default IP address. So, change your computer's IP address to 192.168.0.100 and subnet mask to 255.255.255.0.

Remember to return your computer to its original IP settings when you're done, otherwise this may cause issues on your LAN.

3. You can find GMAC-5 on your computer network by running the Discover.NET software, which is compatible with Windows XP and later Windows releases. Discover.NET can be downloaded from “http://www.gamatronic.com/gmac-5.html”. The software is very easy to use, and it lists all Gamatronic devices in the current subnet.

4. Type the device's IP address in to web browser's address bar and press enter. You should see the main web interface screen. This is the place to begin the configuration.

Figure 4: The main web interface screen

See chapter 5 for further important details on the software configuration process.

3. USER INTERFACE

The User Interface (UI) is built for quick and intuitive access. The usual page structure is:

Figure 5: Layout of the user interface screen1. Company logo, name, and the current firmware version, required for support purposes.

2. UPS, volt-free contacts, environment, and other system indicators showing current status.

3. Language selector, functional on all pages. Language setting is saved with a "cookie" in your browser.

4. Navigation tree lets you efficiently switch between various informational and configuration pages. Items in navigation tree can vary depending on system configuration.

5. All data related to the current informational or configuration page is shown in the middle of the screen.

6. Messages about system-wide conditions may be displayed in the status bar.

3.1 Dynamic updates The web pages are dynamically updated every 3 seconds. This auto-refresh process stops after 5 minutesof no mouse activity so as not to create unnecessary network traffic, and a message will be shown in status bar (item 6 in Figure 4). When the page has stopped refreshing data, it will still display the last information received on the screen. Keep in mind that that this information may already be obsolete.

To restore the dynamically updated connection, just refresh the page in your browser.

8 GMAC-5 User Guide

3.2.1 UPS / Power System To monitor a UPS or other power system, a serial connection to the device in question must be established. This is done by connecting the device to be monitored to the serial connector on the GMAC-5’s rear panel, and configuring the connection in GMAC-5, using the “Serial” option in the “Configuration” menu.

When UPS monitoring is thusly enabled, the “UPS” menu option displays the UPS’s status and general information. The “Measurements” and “Commands” options display additional information, and enable the user to send commands to the unit, to switch it on or off, or to run a test, and so on.

Be aware that the information displayed and the commands supported depend on the specific UPS or power system model. Not all UPSs support every possible command.

3.2.2 Log The log menu shows you the total amount of events saved in the log, and will offer to either download the log to your computer (as a csv file) or clear it. Some systems, like Power+ modular UPS units, have their own internal log, and in such cases the log screen will enable you download that internal log as well.

3.2.3 Configuration The configuration menu functions are described in detail in chapter 5.

10 GMAC-5 User Guide

4. ADDITIONAL FEATURES

4.1 Automated shutdown of computers If a UPS is being monitored by GMAC-5, and that UPS is providing power to computers, you can instruct GMAC-5 to shut down any of those computers in an orderly fashion in the event of a prolonged ac input failure, before the UPS’s battery is exhausted. To achieve that you must install Shutdown Agent software on the computers to be shut down. The Shutdown Agent can be downloaded through a link on the remote shutdown configuration webpage (see section 5.6), or can be obtained from your GMAC-5 dealer. Use the same configuration webpage to configure remote shutdowns.

Remote computer shutdown can also be achieved through special dedicated software installed on one of the servers. Such software monitors the UPS through SNMP, and can be configured to send appropriate shutdown signals to specific servers in response to a specific alarm condition. Such software may provide more shutdown options.

4.2 The bootloader Bootloader mode is used to upgrade GMAC-5’s system software, and to upload a previously saved GMAC-5 configuration.

There are two ways to put GMAC-5 into bootloader mode:

• Use the “Switch to bootloader” button in the Configuration screen on the web interface (Figure 10);

Figure 10: Bootloader mode button

OR • Reset (or power-on) the device while pressing the “Act” button.

In both cases, the unit will switch on in bootloader mode with the user-defined IP setting (see section 5.1 “Network configuration”). By default, the unit then automatically attempts to receive a DHCP address. Failing this it will use the static address (as found in the “Network > configuration” screen). The default static address is 192.168.0.198 class C. The unit will then be discoverable with Discover.NET software within a given subnet (broadcast).

After 5 minutes in bootloader mode without user activity, bootloader exits (try to run the main program). If the main program has not been flashed properly, the unit reboots again in the bootloader mode to let you try to upload the new firmware again. If you are having trouble with a system upgrade, please contact support.

4.2.1 Using bootloader mode Using a web browser, put the GMAC-5 in bootloader mode by pressing the “Switch to bootloader” button in the "Configuration" webpage (see Figure 10). Then follow the simple screen prompts to perform the required function.

Page 15: gmac-5 user guide

GAMATRONIC ELECTRONIC INDUSTRIES LTD.

GMAC-5 User Guide 11

Figure 11: The bootloader login screen

User name and password will match the ones set up in the main program. Default username and password are "admin" and “admin”, and are case sensitive.

The next page will offer you to upload a file. After choosing a file and pressing "Upload" let the upload finish, do not navigate away or refresh the page until you're informed that the upload is complete.

Figure 12: Using the bootloader to update a file

The bootloader can work with three file types. The valid file extensions are:

• .gam – Web UI software update files • .bin – Firmware update files • .mem – System settings files that were previously saved through the by using the

“Download” button on the Configuration main screen

Page 16: gmac-5 user guide

GAMATRONIC ELECTRONIC INDUSTRIES LTD.

12 GMAC-5 User Guide

4.2.2 Upgrades You will not have to upgrade the software unless serious issues are reported and fixed. Your distributor will contact you if a critical update is required. Never try to upload any *.gam or *.bin files unless instructed to do so by an authorized distributor or the manufacturer.

Usually, the web user interface file version must exactly match the specific firmware file version, and therefore you will be asked to upload both .bin and .gam files for an upgrade. Do not change the names of the files you receive for upgrade. The bootloader will only accept English letters and numbers in the uploaded file name. The only valid file extensions are “.gam”, “.bin”, and “.mem”.

To perform an upgrade, just choose the relevant file (normally the .bin file goes first) in the upload page and press the "Upload" button. After you are informed that the upload is finished, choose to upload another file if required. After all files have been uploaded, press the "Reset" button to return to normal operation.

4.2.3 Saving system settings You can save the current system configuration values from the "Configuration" web page by selecting the “Download configuration” button. The configuration will be downloaded with the name “config.mem” to the location of your choosing. You can rename the file if you like, but use only Latin (English) letters and numbers in the file name, and do not change the “.mem” extension, otherwise you may have issues uploading it in the boot loader on a later stage.

When you need to restore the configuration, simply choose the file through the bootloader upload page and press the "Upload" button. After you are informed that the upload is finished, press the "Reset" button to return to normal operation.

5. CONFIGURATION All system configurations are performed under the configuration menu. Use this menu to update basic system settings like identification names, and to quickly enable or disable system functions without removing the functions from the current configuration.

The Identification information entered on this screen (Unit name, Site, Manager) appears on the main screen upon entry into the system. This is to enable you to distinguish between units in the event that you are operating multiple GMAC-5 units.

Figure 13: Configuration menu expanded

There are also three buttons near the top of the screen:

• DOWNLOAD CONFIGURATION: downloads to your computer a configuration file that can be kept for future uploading through the bootloader to restore system configuration to the same state. The restore works only if the system is of the same software version as was in effect at the time the configuration backup file was created (unless otherwise mentioned in the documentation for the new software release).

• RESTORE TO FACTORY DEFAULTS: returns GMAC-5’s configuration to default factory settings excluding password. To restore the factory default user name and password (admin/admin) see section 1.5.2.

• SWITCH TO BOOTLOADER: causes GMAC-5 to reboot in bootloader mode. You must refresh the page manually to see the bootloader web interface. It is possible that when switching to bootloader mode the device will receive a different IP address. In bootloader mode GMAC-5 takes its IP address as per the user’s instruction in the “Actual IP address” field in the “Configuration > Network” screen (see section 5.1 “Network configuration”).

Using Telnet to modify configuration parameters GMAC-5’s built-in graphic user interface described in this chapter is the preferred method for setting and modifying the values of the configuration parameters. However, it is also possible to use Telnet for this purpose.

Start up Telnet and connect to GMAC-5’s IP address. You will be prompted for a valid username and password.

14 GMAC-5 User Guide

After logging on, use the “help” command to display a list of the available functions and their command syntaxes.

5.1 Network configuration Use the “Network” configuration function to specify the details of your connection to the local Ethernet network.

Under "Static IP address" specify the connection details to be used by GMAC-5 when no DHCP address is available, or when you specify that the static address is to be used at all times.

Under "Actual IP address" select the desired mode of operation, which can be one of the following:

• Static IP • DHCP, fallback to static IP • Device IP, fallback to DHCP • Device IP, fallback to static IP.

In the operation modes listed above:

• Static IP is the IP address defined under "Static IP address", • DHCP is the IP address received from DHCP server automatically, and • Device IP is the IP address received from the controller of connected power system (if supported

by protocol), such as the Power+ UPS.

GMAC-5 User Guide 15

5.2 Date/Time configuration Use the “Date/Time” menu option to set GMAC-5’s internal calendar and clock.

Enter the current time and date, or click on "Get local time" button to update all fields with the current local time from your PC. The update does not take effect until the “Apply” button is selected.

The date and time are used to timestamp entries in the event log.

If you choose to receive network time updates, the device will try to receive NTP time from the server (defined in the Network configuration) every three hours. Pay careful attention to the time zone and DST settings when using network time, since these parameters will not be updated automatically.

If an Internet-based time server is defined, make sure that GMAC-5 has access to the Internet.

"Set current time from SNTP server" will simply try to access the server immediately and return a reply. This will also instantly update system time upon successful reply.

16 GMAC-5 User Guide

5.3 Configure a serial connection The “Serial” function is used to describe GMAC-5’s communication link with a UPS or other power system.

Select the protocol and additional serial communication settings. Use the GMAC-5 compatibility table (Table 8) to find out what protocol is supported by your device.

If you are not sure of the particulars of the connection, use the "Detect" button, which will “talk to” the power system to determine what protocol it supports. The speed of the power system’s response to the Detect function can vary. Watch the screen for messages from the auto-detection process. If the Detect function succeeds, all of the fields in the screen are automatically updated with required values – there is no need to click "Apply" after detection, detected values (or "Disabled" if nothing was detected) will be saved automatically.

5.6 Define a shutdown target Use this screen to define a network-connected computer that is to be automatically shut down under certain conditions.

In order for the shutdown to take place, the Shutdown Agent must be installed on the target computer. The Shutdown Agent can be downloaded from the link on this screen, or can be obtained from your dealer.

Figure 21: Define a shutdown target

Table 7: Key to Figure 21 FIELD NAME DESCRIPTION

Target address

IP address or name of the computer to be shut down. The command is sent in UDP; the default port is 262. You can set a different port by adding a colon and the alternate port number after the name or the address. Be sure to configure the Shutdown Agent on the remote computer to use the same UDP port.

On ac input failure Following an ac input failure, a shutdown command is sent to the target computer after the specified time interval.

On low battery Following a low-battery alarm, a shutdown command is sent to the target computer after the specified time interval.

On alarm group Following the occurrence of any of the alarm conditions in the indicated alarm group, a shutdown command is sent to the target computer after the specified time interval.

Wake-on-LAN

Specify a time interval and the target computer’s MAC address. The target computer will receive a “wake up” command after the specified time interval following return of the ac power mains. Use port 7 or 9 as instructed by your network manager. The MAC address can be entered in the format “01:23:45:67:89:AB”, or with dashes instead of colons. The MAC address field is case insensitive. Note: The wake-on-LAN function will work only if the GMAC-5 unit did not lose power during the power outage (i.e., the UPS did not turn itself off).

5.7 Define a username and password Access to the GMAC-5 system can be password protected. Use this screen to define or update a username or to change a username’s password.

Only one username-and-password combination exists at any given time.

The factory default values for the username and password are “admin” and “admin”.

Deselecting the checkbox labeled “Secure web login with password” makes entry of a username and password mandatory for changing settings. This checkbox is deselected by default.

Figure 22: Define or update the username and password for access to GMAC-5

5.7.1 Restoring the factory default username and password • The factory default values for the system user name and password are “admin” and “admin”. • On the initial screen of the “Configuration” function (Figure 23), there is a button labeled “Restore to

factory defaults”. Using this button does NOT restore the username and password to the factory default values.

Figure 23: This button does NOT restore the default username and password

• To restore the factory default username and password values (“admin” and “admin”), see

section 1.5.2.

5.9 Define event properties The “Events” configuration option is used to determine the conditions that will be reported to the user and logged to the event log. The conditions include events related to the status of the UPS or other power system, the status of the power system’s serial link with GMAC-5, the status of the GMAC-5’s input and output voltage-free contacts, and more.

The events screen includes multiple pages of events. The exact number of events will vary, depending on the specific UPS or other power system being monitored and on the GMAC-5 functions currently enabled. Each individual event can be enabled or disabled. A disabled event is not reported to the user and is not logged to the event log.

Figure 25: The Events screen

5.9.1 Event severity Each event has a default status that can be changed by the user. The status can be:

• Informational – Lowest severity. An informational message. • Warning – Next-highest severity. Indicates a potential problem. • Critical – Highest message severity. Warns of a more serious problem.

5.9.2 Message Group In the “Group” column of the Events screen you assign an event to a group. The group name is used by GMAC-5 to handle related messages together. In the “Recipients” screen (see section 5.8) you indicate which message group or groups you want each recipient to receive.

The system default values include two message groups: Power and System, plus six generic group names (Group #3 through Group #8). You can use the “Groups” screen (section 5.10) to define additional message groups and to change the name of an existing message group.

7. PREVENTIVE MAINTENANCE Every Gamatronic communications product contains technologically advanced electronic systems. These electronic systems are sensitive to environmental conditions. It is important that the operating and storage environments of the power system be clean and dust-free, free of dampness and excess humidity.

GMAC-5 requires periodic preventive maintenance inspections. At the least, these inspections should include a visual inspection of the GMAC-5 and the tightening of any screws that have over time become loosened.

Gamatronic bears no liability for damage caused to the power system due to improper maintenance by third parties, in particular after the expiration of the warranty or service agreement.

It is the responsibility of the power system’s owner to uphold his responsibilities according to the warrantee or service agreement. This includes ensuring that the power system’s environment meets requirements.

8. SERVICE AND REPAIRS Gamatronic maintains a team of service technicians, repair laboratories, and an ample inventory of spare parts, dedicated to the service and repair of our products. When service is required, it will be performed either at the customer's site or in one of our laboratories, according to the judgment of our technician and the specifics of the service agreement between the customer and Gamatronic.

In regards to service, oral agreements have no standing. Service shall be provided gratis during the warrantee period, on the condition that the power system has been properly maintained and a written record has been kept of any maintenance performed on the system.

The initial warrantee period can be extended by a written service agreement between Gamatronic and the customer. Without a written agreement, Gamatronic is under no obligation to provide service after expiration of the initial warrantee period.

Gamatronic will not be responsible for maintenance or changes to the power system that are performed by an agent without written authorization from Gamatronic.
