Did you ever figure out how to reset the password?



Re: set default 3Com X5

Try requires physical access to the unit.

- Make a console connection to the x5/x506

- Power on the unit. Let it show CPU, memory etc.

- When the screen shows "Loading" (before the dots appear) - quickly type "mkey" (no quotes) - and press enter

You can then add a new Super Admin account

Note, you have a very small window in which you can actually type don't sweat if it doesn't work on the first attempt.

I only tested this on an X5 though, on TOS version TOS Version     : X3.1.0.2098

If it works, you should see this right after typing Mkey once the 'loading' status appears (takes a few minutes, goes through CPU, memory, etc etc.:


There are three security levels for specifying user names and passwords:

  Level 0: User names and passwords are unrestricted.

  Level 1: Names must be at least 6 characters long; passwords at least 8.

  Level 2: In addition to level 1 restrictions, passwords must contain:

             - at least 2 alpha characters

             - at least 1 numeric character

             - at least 1 non-alphanumeric character

Please specify a security level to be used for initial super-user name

and password creation.  As super-user, you can modify the security level

later on via Command Line Interface (CLI) or Local Security Manager (LSM).

You can continue from there.

Note: I do not know if this has an adverse affect on config. Mine was OK, but I was factory resetting it be careful.
