Problem: How to reset password on switch 2948
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> reset -sysreset
At this point the password has been reset.
