Step 1: Type show to determine which slot the MSFC card is in. 

The MSFC module will be in slot 15 or 16.
The MSFC is a daughter card that is installed on the supervisor engine. 
Slots 15 and 16 are logical slot numbers for the MSFCs, which  are installed on the supervisors in Slot 1and 2 respectively.
Note: If you are running in redundant mode the MSFC, which needs a password recovery, must be the active supervisor engine.
