Loading host software
Follow these steps to load the host software:
Step 1: Select <1> in BOOT Menu and press <Enter>. The system displays the following information:
1. Set TFTP protocol parameter
2. Set FTP protocol parameter
3. Set XMODEM protocol parameter
0. Return to boot menu
Enter your choice(0-3):
Step 2: Enter 3 in the above menu to load the host software by using XModem.
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.
