17Repeat step 12 through step 16 to download the next file and avoid a transfer time-out error if you are downloading both the firmware and HTML files.

The download is complete when the UI displays:

If the firmware update fails, the UI displays an error code indicating the cause. The AP automatically resets after all file transfers are completed.

18Exit the communication program to terminate the session.

19Repeat this process for other APs in the network.

Auto Upgrade all APs The Update ALL Access Points feature upgrades or downgrades the firmware of all

Via Messaging associated APs with the same WLAN Service Area on the same subnet and includes all recognized hardware platforms regardless of firmware version. The initiating AP sends the correct file name for each 3Com platform. The initiating AP does not send update commands to non-3Com platforms.

You can find the specific APs that have firmware upgraded or downgraded in the Known APs window. There is a 2-second time interval between the WNMP update firmware commands for updating each AP. This interval prevents more than one AP from accessing the TFTP server at once and causing network congestion.

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:

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 (see “Changing the Access to the UI” for more details). The AP generates the Main Menu.

4Select Special Functions from the Main Menu.

5Select Alter Filename(s)/HELP URL/TFTP Server and press Enter.

6Type the firmware file name in the Download Filename field.

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. (See step one)

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

8Press Enter.

9Select Save Configuration to save settings.
