Move the switch at stable and consistent paces with your peer. Keep balance of your body. Hold the handles on both sides of the chassis, instead of power handles or the vent of the chassis when moving the switch. Since the power handle or the vent is not designed to bear the weight of the entire chassis, the switch may get damaged or even your body may get hurt if you hold these parts to move the switch.

burned.
Page 74: Temperature/Humidity Requirements
To ensure the normal operation and service life of a switch, a certain level of temperature and humidity should be maintained in the equipment room. If the humidity in the equipment room is too high for a long time, it will lead to bad insulation of the insulating material or even creepage. Sometimes, the mechanical performance changes of material, the rustiness and corrosion of some metal parts are also likely to occur.
Page 75: Anti-Static Requirements
For better heat dissipation and equipment maintenance, it is recommended that the front and back of the switch should be at least one meter away from walls or other devices, and that the left and right of the switch should be at least 0.8 meters away from walls. If a rack is to be installed, the headroom should be 3 meters at least.
Page 76: Installation Tools
Make sure that the switch fits the rack size. Leave some spaces beside the left and right panels of the switch for chassis heat dissipation. Installation Tools Table 2-4 Required installation tools list Type Name Tools Measure and Long tape, ruler (of 1 meter), gradienter, marking pen,...

Mount the cable rack and mounting ears on the switch. Together with another person, carry the switch to the front of the cabinet slowly. Lift the switch a little above the weight-bearing guide rails and put it on the guide rails and adjust its position.
Page 80: Mounting A Switch On A Workbench
Other grounding environment The following figures are sketch maps, and just show the way of cable connecting rather than the real layouts. Hereafter introduced some methods for grounding the switch in different environment.
Page 81 If there is no grounding strip but earth nearby and the grounding body is allowed to be buried, you can simply hammer an angle iron or steel pipe no shorter than 0.5m into the earth. In this case, the yellow-green protection grounding cable should be welded with the angle iron (steel pipe) and the joint should be processed against eroding.
Page 82: Installing Switch Modules
If there is no grounding strip and no grounding body can be buried, the DC-powered Ethernet switch can be grounded through the return (RTN) wire of the DC power supply. In this case, make sure the RTN wire has been well grounded from the DC egress of the DC power cabinet.

Page 89: Connecting The Aux Cable (Optional)
Take the following steps to connect the console cable, when configuring the switch on the terminal. Plug the DB-9 female plug of the console cable to the serial port of the PC or the terminal where the switch is to be configured.
Page 90: Connecting Category-5 Cables
Figure 3-14. If the RS-485 port is used, use a straight through cable to connect the COM port with the RS-485 port on the PSE2500-A. The PoE monitoring port on the PSR1400-D is an RS-485 port. You can select a proper connection method for the RS-485 port according to the type of the PoE monitoring port on the external power module.
Page 91 Pins 1 and 2 (negative), 3 and 6 (positive) are used for external PoE power supply. Connection procedure Plug one end of the network cable into the Ethernet RJ-45 jack of the switch to be connected. Plug the other end of the cable into the RJ-45 port of the peer device.
Page 92: Connecting Fibers
Connecting Fibers Introduction to the fiber connector Before connecting the fibers, make sure the type of the connector and the fiber are consistent with that of the optical interface. Fiber connectors are indispensable passive components in optical fiber communication system. Their application enables the removable connection between optical channel, which makes optical system debugging and maintenance more convenient and transit dispatching more flexible.
Page 93: Cabling
For the switches mounted in a 19” standard cabinet or N68 cabinet, the service cables are bound on the cable binding rack at the left side of the chassis and arranged to run on the cabling rack or in the raised floor according to the situation in an exchange equipment room (whether the signal cable of the room is accessed from the cabling rack on the top of the chassis or the cabling rack under the floor.) Collect all...
Page 94: Cable Binding
Figure 3-18 Cable binding example I The radius of the curve at which a cable is bent should be at least twice the cable’s diameter. At the point where a cable runs out of a connector, the radius of the curve at which the cable is bent should be at least five times its diameter.
Page 95 Figure 3-19 Cable binding example II Before bending the cables, bind them first. Mind that no tie binds the bended part of any cables, for fear of cable core breaking due to excessive stress. See the following figure. Figure 3-20 Cable binding example III The spare cables or excessive parts should be folded and bound and located at right places in a cabinet or on the cable channel.

Set bits per second to 9600, data bits to 8, parity to none, stop bits to 1 and flow control to none. Figure 4-4 Set serial port parameters After setting serial port parameters, click OK.
Page 102: Power-On Startup
The console cable has been correctly connected. The computer or terminal for configuration has been started and the terminal parameter settings have been done. Before powering on the switch, make sure where the power switch of the equipment room is located, so that you will be able to power off when meeting accidence.
Page 103: Check After Power-On (Recommended)
You are recommended to check as follows after powering on the switch to ensure the configurations thereafter. After a switch is powered on, the heat dissipation system starts working. You can hear the noise as the fan rotates and feel air flow out from the vent.
Page 104 Press ENTER to get started. The above information indicates the completion of the switch auto-booting. Press Enter and get the following output. By this time, you can start configuring the switch. <3Com> 3Com S7900E series switches provide a variety of command views. For the specific descriptions on the configuration commands and command line interfaces, refer to Configuration Guide and Command Reference Guide of the 3Com S7900E Series Ethernet Switches.

Power modules are installed to/removed from the chassis with power module adapters. In the second scenario, you need to install a power module adapter to the chassis first and then install a power module to the power module adapter. The installation and removal methods in this scenario are the same as in the first scenario.

Page 110: Removing And Installing A Fan Tray
Do not touch any naked wire, terminal or any part of the product labeled with a dangerous voltage to avoid injury. If you want to replace the fan tray of an in-service switch, separate the fan tray from the backplane to disconnect the power and wait for the fan stops rotating before pulling it out completely. Considering that the fan may be still rotating, avoid stretching your hands into the fan tray.

Page 134: Upgrading Using Tftp
Upgrading using TFTP is similar to upgrading using FTP, except that the protocol used for downloading is TFTP. In this case, the switch can only function as a TFTP client to download software from the TFTP server to its Flash. After software is downloaded, the remaining procedure is the same as that in the case of upgrading using FTP.
