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 forgot my admin password
If it's the Power Plus (3C16475BS) model, there should be a reset button inside a small hole on the back. "10 - Recovery Button" Inserting a paperclip or similar to reset. If it's not the Power Plus model and is in fact (3C16475A), this is an unmanaged switch, with no administrative capabilities. You don't need a password.

How do i Reset or break in to get reset my
The resetting of the password requires the installation of a console cable to the console port.
Be sure the terminal emulator program is set to VT-100 management
using compatible, 38400 baud rate, no parity, 8 data bits and Console
connection one stop bit.
Use the included cable, or be sure that the pin-out complies with a standard null-modem cable
Once the cable is connected, reboot the switch. Type a Ctrl/C until
you enter the failsafe mode. This will be denoted with the prompt:
“CFE>”
At the prompt execute the following commands:
CFE> passwrd
CFE> reset -sysreset
At this point the password has been reset.
