Product:

3CBLSG48 - 3Com Baseline Switch 2948-SFP Plus

Fix:

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.
