    Recover the password of a 3COM 4250T switch

    Last weekend, one of my 3com 4250T switches stopped functioning. I used a multimeter and the fuse seems okay, but it's dead as a doorknob. Since my switches are stacked to one virtual unit, I bought a second hand 4250T to replace the broken one.

    As often with second hand crap, this switch contained settings from the last location. Including an unknown password.

    Fortunately, the switches have a recovery mode (which can also be disabled, so below instructions may not work on another switch).

    Recovery mode

    I connected the switch to a RS232 port using a null-modem cable. If you know the switches IP, you can also use telnet.

    Login: recover
    Password: recover

    *** Password Recovery Mode ***
    The administrative password will be cleared if a hard reset operation is
    carried out on the device within 30 seconds.

    If a hard reset operation is not carried out during this period, the device
    will return to the CLI login prompt

    countdown = 30...29...28...

    Pull the plug of the switch before the countdown reaches 0. When you boot it again, you can login using the default user "admin" and simply press enter for 'password'.
