I forgot ip address and password and want to factory reset
Connect the console cable, open a connection to the serial port via a utility such as PuTTY, and do the following:
1) Enter the user name "recover" and password "recover" to place your unit in password recovery mode. The unit will remain in password recovery mode for 30 seconds max.
2) Perform a hard reset by removing power, waiting 10 seconds, and then re-applying power.
3) Once the switch has rebooted, enter a new password for the "admin" user account.
4) Enter enable to leave password recovery enabled, or enter disable to turn it off. You are now logged in as the default "admin" user.
Note: If password recovery has been disabled, the only way to recover access is to return the switch to 3com.

I have 3Com Baseline Switch
First,"There is usually a small button on routers that can be accessed with the tip of a pen or a paperclip. When you find that tiny button, hold your pen or paperclip down on it for approximately 10 seconds until the router resets itself to factory defaults."
After that, you can contact the manufacturer to get some helps if you still have problem.

I have two 3com
I don't know anything about these units, nor do I have time to source any docs for you, but maybe you can try connecting a PC directly to the port your patch panel is connecting the the switch from, you can at least see if that port is working.
My next and only other suggestion is to invest in a "LAN cable tester". In my area, you can find cheap ones for U$20.
The tester will allow you to check connectivity between any two ports, and allows you to test both patch links and individual CAT5/6 cables.
