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 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. Good luck!

notify the police dept / person handling the case and let them know about the face book information

Use a brute force password solver or at best do a reset

1 Remove power from the Gateway. 2 Disconnect all your computers and the cable/DSL modem from the Gateway router. 3 Using a straight through Ethernet cable, connect the Ethernet Cable/DSL port on the rear of the Gateway to any one of the LAN ports. 4 Re-apply power to the Gateway. The Alert LED will flash as the Gateway starts up, and after approximately 30 seconds will start to flash more slowly (typically 2 seconds on, 2 seconds off). Once the Alert LED has started to flash slowly, remove power from the Gateway. 5 Remove the cable connecting the Cable/DSL port to the LAN port, and reconnect one of your computers to one of the Gateway LAN ports. 6 Re-apply power to the Gateway, and when the start-up sequence has completed, browse to: http://192.168.1.1 and run the configuration wizard.

If I remember correctly, there is a tiny hole at the back or on the side. Press a paper clip into it. The switch should do a full reset and then reboot. If its just locked up, I would switch off at the power for 15 mins and try let it do an auto restart itself. Do this before you go doing a full button press reset as you may lose any or all updates the switch has had loaded into it.

Are you able to remove the card from your PC? and read the model on it? Are you able to find your motherboard/computer model? use the motherboard/computer model to find what model of card is on it. Once you have the nic model search for a driver.

From Digium Mailing List: 3Com 3100 series phones do not support SIP with non-3Com systems. They have a basic boot loader which must download code from a 3Com NBX or a 3Com VCX system. If you don't have either of these, then you won't get runtime code on the phone, thereby making it impossible to use the thing with Asterisk. Asterisk Users 3Com Phones
