You will have to reset the switch and intercept the boot into ROMON mode, then load the config file and change the console password, wright the mem and reload.

If you have the password logon and type wr erase and reboot.

Due to the length of the solution I have provided you with a link to the Cisco site on how to reset catalyst switches.

It is not a simple process and you need to read the instructions carefully.

It's possible that the management port is on another VLAN or is not enabled. Your most reliable bet is to try a serial connection to console in.

Alternatively, there is a procedure that will work even if you don't know the password:

Not sure what Cat switches you have, but the cajun switch must use the same trunking encapsulation.  Older catalyst switches use ISL trunking which only work with Cisco switches.  Make the port between the lucent and cisco dot1q encapsulation on the cisco trunk port.  Also turn on debugging on the cisco and see what messages are generated.
