not have a TFTP server, you can install the one shipped with the access point. Use 
the 3Com CD (Tools and Utilities options) to install the 3CDaemon TFTP server.

You must supply the IP address of the TFTP server computer. The default TFTP 
client port number is 69, the TCP/UDP port number that is most commonly used 
for TFTP, although you can change this to a different port number if required. 

The System Log page lets you set up one or two computers for saving log files and 
to enable or disable logging. Log files are not viewable through the Configuration 
Management System or the access point, and so must be accessed from a host 
computer running a syslog server.

By default, logging is off. If you turn on logging, you must specify at least one 
host. The access point sends log information to the host using syslog through port 
514 (the TCP/UDP port number that is most commonly used for syslog).

If you do not have a syslog server, you can install the one shipped with the access 
point. Use the 3Com CD (Tools and Utilities options) to install the 3CDaemon 
syslog server.

You can download system firmware upgrade files from the 3Com Web site at 
http://www.3com.com and install those upgrades on the access point. You must 
have a TFTP server set up on which to store the upgrade file. This is the server 
specified on the TFTP setup page.

To avoid problems that could occur if a wireless association were interrupted 
during the upgrade, it is recommended that you perform the upgrade from a 
computer that is wired to the LAN.

To locate an upgrade file and download it to your computer:

1 Log on to the 3Com Web site at http://www.3com.com.

2 Navigate to the product support page.

3 Navigate to the software download page and locate the file you want 

to download.

4 Follow the instructions to download the file into a directory on your computer.

5 Copy or move the file to the TFTP server upload/download directory.

To install an upgrade:

1 Back up the configuration.

Under Backup/Restore Configuration, click Backup Configuration. For details, see 
“Backing up Configurations” on page 33.

2 Under Tools, click Upgrade System. 

3 In the Upgrade System page, make sure the TFTP server IP address is correct.
