Local Boot ROM and Software Loading 475
The subsequent steps are the same as those for loading the Boot ROM, except
that the system gives the prompt for host software loading instead of Boot ROM
loading.

You can also use the xmodem get command to load host software through the
Console port (of AUX type). The load procedures are as follows (assume that the
PC is connected to the Console port of the switch, and logs onto the switch
through the Console port):
■ Step 1: Execute the xmodem get command in user view. In this case, the
switch is ready to receive files.
■ Step 2: Enable the HyperTerminal on the PC, and configure XModem as the
transfer protocol, and configure communication parameters on the Hyper
Terminal the same as that on the Console port.
■ Step 3: Choose the file to be loaded to the switch, and then start to transmit
the file.
Loading by TFTP through
Ethernet Port
Introduction to TFTP
TFTP, a protocol in TCP/IP protocol suite, is used for trivial file transfer between
client and server. It is over UDP to provide unreliable data stream transfer service.
Loading the Boot ROM
Figure 162 Local loading using TFTP
Step 1: As shown in Figure 162, connect the switch through an Ethernet port to
the TFTP server, and connect the switch through the Console port to the
configuration PC.
n
You can use one PC as both the configuration device and the TFTP server.
Step 2: Run the TFTP server program on the TFTP server, and specify the path of the
program to be downloaded.

CAUTION: TFTP server program is not provided with the 3Com Series Ethernet
Switches.
Step 3: Run the HyperTerminal program on the configuration PC. Start the switch.
Then enter the BOOT Menu.
At the prompt "Enter your choice(0-9):" in the BOOT Menu, press <6> or
