The Ethernet TFTP upgrade method requires a connection between the AP and PC
on the same Ethernet segment. Verify the PC has a TFTP server running on it.
Running the server requires third party software such as FTP PC/TCP for DOS or
OnNet™ for Windows. The wireless TFTP upgrade method requires a connection
between the AP and a TFTP server. The TFTP server can be running on a 3Com
AirConnect device.
Updating the firmware requires that a TFTP server be running in the background.
To update the AP firmware using TFTP, do the following:
1 Copy the firmware files dsap_fw.bin and 3cap_htm.bin to the terminal or PC
hard disk.
2 Telnet to the AP using its IP address.
3 Type the case-sensitive password at the prompt, which generates the Main Menu.
4 Select Special Functions from the Main Menu.
5 Select Alter Filename(s)/HELP URL/TFTP and press Enter.
Type the firmware file name in the Download Filename field..
The remainder of this procedure uses Windows 98 as an example.
6 Only change this file name if you are required to do so. The default file names are
dsap_fw.bin and 3cap_htm.bin. Verify that the path to the files is accurate.
7 Enter the TFTP Server IP address in the TFTP Server field.
8 Press Enter.
9 Select Save Configuration to save settings.
10 Select Special Functions from the Main Menu.
11 Select Use TFTP to Update Access Points and press Enter., which generates the
following prompt:
"Are you sure (Y/N)?"
12 Type y. The Telnet session ends when you type y at the prompt. The WIRED LAN
ACTIVITY indicator on the AP does not flash. The AP resets when the file transfer
and flash programming complete.
13 Telnet to the AP using its IP address.
14 Type the case-sensitive password at the password prompt, which generates the
Main Menu.
15 Verify the accuracy of the version number on the System Summary window.
16 Press Ctrl+D to end the Telnet session.
17 Repeat this process for other APs in the network.
The Xmodem upgrade method requires a direct connection between the AP and
PC using a null-modem serial cable and software such as HyperTerminal for
Windows 95. Xmodem supports file transfers between terminal emulation
programs and the AP UI. Xmodem transfers require more time than TFTP transfers.
