Page 20: Installation Preparations
Installation Site The 3Com Baseline Switch 2900 Family must be used indoors. You can mount the switch in a rack or on a workbench, but make sure: Adequate clearance is reserved at the air inlet/exhaust vents for ventilation. -
Page 21: Electromagnetic Susceptibility
Use electromagnetic shielding, for example, shielded interface cables, when necessary. Route interface cables only indoors to prevent signal ports from getting damaged by over-voltage or over-current caused by lightning strikes. Laser Safety The 3Com Baseline Switch 2900 Family are Class 1 laser devices. -
Page 22: Installation Tools
When an SFP module on the 3Com Baseline Switch 2900 Family is operating, do not stare into the optical port because the laser light emitted from the optical fiber may hurt your eyes. Installation Tools Flat-blade screwdriver Phillips screwdriver ESD-preventive wrist strap... -
Page 23: Installing A Switch
Installing a Switch On a mounting screw of the chassis of the 3Com series switches, there is a seal labeled. You need to keep it intact before asking the agent to maintain the switch. You need to get the permission of the local agent before you can open the chassis. -

Page 28: Mounting The Switch On A Workbench
Mounting the Switch on a Workbench In many cases, standard 19-inch cabinets are not available. Therefore, switches are often placed on clean workbenches. To place the switch on a workbench, follow these steps: Step1 Place the switch with bottom up carefully, and then clean the round holes on the chassis bottom with dry cloth. - Page 29 Figure 3-10 Connect the PGND cable to the grounding hole of switch (1) Rear panel of the switch (2) Grounding sign (3) Grounding hole (4) OT terminal (5) PGND cable (6) Grounding screw To attach the other end of the PGND cable to the grounding strip in the equipment room, follow these steps: Step1 Cut the PGND cable to a proper length according to the distance between the switch and the grounding strip.
-
Page 30: Where A Grounding Conductor Can Be Buried
The PGND cables supplied with the 3Com Baseline Switch 2900 Family do not provide OT terminals at the ends connecting the grounding strip. You need to prepare proper OT terminals by yourself. The fire main and lightning rod of a building are not suitable for grounding the switch. The PGND cable of the switch should be connected to the grounding device for the equipment room. -
Page 31: Connecting The Power Cord
Connecting the Power Cord Connecting an AC Power Cord The 3Com Baseline Switch 2900 Family uses an external AC power system for its power supply. Follow these steps to connect an AC power cord: Step1 Connect one end of the supplied PGND cable to the grounding screw on the rear panel of the chassis and the other end to the ground as near as possible. -
Page 32: Connecting An Rps Dc Power Cord
Make sure that the PGND cable has been properly connected before powering on the switch. Connecting an RPS DC Power Cord The 3Com Baseline Switch 2928-HPWR Plus also supports RPS DC power input with the input voltage ranging from –52 V to –55 V. Follow these steps to install a DC power cord: Step1 Connect one end of the supplied PGND cable to the grounding screw on the rear panel of the chassis and the other end to the ground as near as possible. - Page 33 The selected power module matches that required by the switch. The power cables are properly connected. All the interface cables are cabled indoors. If there is any cable wired outdoors, verify that socket strip with lightning protection and lightning arresters for network ports have been properly connected.

Page 45: Loading Files Using Xmodem Through Console Port
The items in the Boot ROM menu are described in Table 4-2 Currently, Boot ROM files are not provided separately by the 3Com Baseline Switch 2900 Family; instead, they are stored together with application files in the files with the name extension of .bin. - Page 46 Task Remarks Required Set the download rate of the console port on the Log in to the switch through the HyperTerminal switch and then set the download rate of the console port on the switch. Optional Set the baud rate of the serial port on the terminal Change the rate of the serial port on the terminal to be consistent with that of the console port on the switch.
- Page 47 After the system displays “Enter your choice(0-3):”, enter 1 to enter the protocol parameter setting menu. All the Boot ROM files to be loaded are complete Boot ROM files. 1. Set TFTP protocol parameter 2. Set FTP protocol parameter 3. Set XMODEM protocol parameter 0.
- Page 48 Now that the console communication baud rate of the switch has been changed to 115200 bps while that of the terminal is still 38400 bps, the two sides cannot communicate with each other. According to the prompt, you need to change the baud rate of the terminal to 115200 bps. Typically, the size of a .bin file is over 9 MB.
- Page 49 Figure 5-2 Properties dialog box Figure 5-3 Modify the baud rate Step3 Select Call > Call to reestablish the connection.
- Page 50 Figure 5-4 Reestablish the connection The new settings can take effect only after you reestablish the connection. Establish a connection between the terminal and the switch using the changed rate Press Enter to reestablish the connection between the terminal and the switch and download the application file at 115200 bps.
- Page 51 Figure 5-6 File transmission dialog box Step2 Click Send. The following dialog box appears: Figure 5-7 Send the application file using XMODEM Updating the Boot ROM file on the switch After the Boot ROM file is downloaded, the terminal displays the following information: Loading ...CCCC Done! Will you Update Basic BootRom? (Y/N):Y The system asks you whether you want to update the basic Boot ROM section.
- Page 52 Set the baud rate to 38400 bps (refer to “Change the rate of the serial port on the terminal” on page for detailed operation). If you select 38400 bps as the download rate, skip this step, that is, you do not need to modify the baud rate of the HyperTerminal.

Page 53: Loading Files Using Tftp Through Ethernet Port
Loading Files Using TFTP Through Ethernet Port Introductin to TFTP Trivial File Transfer Protocol (TFTP) is a TCP/IP protocol used for file transfer between client and server. It provides a simple and low-overhead file transfer service. TFTP provides unreliable data transfer over UDP. - Page 54 The PC and the TFTP server can be the same device. Run the TFTP Server program on the sever Run TFTP Server on the server connected with the switch’s Ethernet port, and specify the path of the application file to be downloaded. Run the terminal emulation program on the PC connected with the switch’s console port.
- Page 55 Enter the file name and IP addresses based on the actual condition. If the switch and the server are on the same network segment, you can specify any unused IP address of the network for the switch without specifying the gateway’s IP address; if they are not on the same segment, you need to specify the gateway’s IP address so that the switch can communicate with the server.
-
Page 56: Loading Files Using Ftp Through Ethernet Port
The procedure of loading an application file is similar to that of loading a Boot ROM file. The difference lies in that the system displays the prompt of loading the application file rather than the Boot ROM file. After loading the application file, the switch displays that you should configure the application attribute, that is, main, backup, or none. - Page 57 Set up the configuration environment Connect an Ethernet port of the switch to the server (whose IP address is available) that provides the file (usually the .bin file) to be downloaded, and connect the console port of the switch to a PC, as shown in Figure 5-9.

Page 60: Maintenance And Troubleshooting
Maintenance and Troubleshooting File Loading Failure If file loading fails, the system runs steadily using the original system files. In this case, check whether the physical ports are properly connected. If not, reconnect them correctly and restart the loading procedure. If so, view the loading procedure information displayed on the HyperTerminal to check for input errors. -
Page 61: Power Supply Failure
Power Supply Failure The 3Com Baseline Switch 2928-HPWR Plus adopts AC power input, RPS power input, or both RPS and AC power inputs. Other 3Com Baseline Switch 2900 Family adopt AC power input only. You can determine whether the power system of a switch functions normally by viewing the power LED or RPS power LED on the front panel. -
Page 62: Configuration Terminal Failure
The RPS power input is normal. If the cause cannot be located in the preceding steps and the problem persists, contact your local sales agent or service engineer. Configuration Terminal Failure After the switch is powered on and the system is normal, the booting information will be displayed on the configuration terminal.
