74CHAPTER 6: CONFIGURING THE AP USING THE ASCII INTERFACE

Update using TFTP 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:

1Copy the ﬁrmware ﬁles dsap_fw.bin and 3cap_htm.bin to the terminal or PC hard disk.

2Telnet to the AP using its IP address.

3Type the case-sensitive password at the prompt, which generates the Main Menu.

4Select Special Functions from the Main Menu.

5Select 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.

6Only 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.

7Enter the TFTP Server IP address in the TFTP Server ﬁeld.

8Press Enter.

9Select Save Conﬁguration to save settings.

10Select Special Functions from the Main Menu.

11Select Use TFTP to Update Access Points and press Enter., which generates the following prompt: “Are you sure (Y/N)?”

12Type 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.

13Telnet to the AP using its IP address.

14Type the case-sensitive password at the password prompt, which generates the Main Menu.

15Verify the accuracy of the version number on the System Summary window.

16Press Ctrl+D to end the Telnet session.

17Repeat this process for other APs in the network.

Updating using The Xmodem upgrade method requires a direct connection between the AP and Xmodem 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.
