Hi,
Depending on the Supervisor Module model, most likely it's a standard Cisco's "password recovery procedure":
Connect to the console
Reboot the switch (power cycle)
Start pressing Ctrl-C till you get to the BOOTROM
Change boot configuration register to 0x2142 (confreg 0x2142)
Boot the switch. It will ignore confuguration and boot "empty".
Go to "enable mode".
Copy startup configuration to running configuration ("copy start run")
Change boot register back to 0x2102 (conf t -> conf 0x2102)
Write config (write mem)
Reboot
Good luck,
