MSFC Missing

The same logic and reasoning that was used in troubleshooting Supervisor modules applies here as well. The first thing to do when the MSFC disappears is to console into it. The switch console command, running Catalyst OS software, allows the console screen to switch from the Supervisor to the local MSFC. In other words, if you are consoled in Supervisor module 1, you can console to MSFC 15, but not MSFC 16, which is on Supervisor module 2. Execute Ctrl^C^C^C to switch back to the Supervisor. The following steps outline how to recover an MSFC missing from the chassis:

Step 1. Switch from the Supervisor console to the MSFC console:

Switch1 (enable) switch console 

Trying Router-15...

Connected to Router-15.

Type ^C^C^C to switch back...

Step 2. Check what IOS images are currently available on the bootflash:

rommon 3 > dir bootflash:

         File size           Checksum   File name

   1688336 bytes (0x19c310)   0x786a3e5f    c6msfc2-boot-mz.121-8b.E11

  12278476 bytes (0xbb5acc)   0x91074cd4    c6msfc2-jsv-mz.121-8b.E11

Step 3. After selecting which IOS image to use, use the boot bootflash command to load the image on the MSFC:

rommon 4 > boot bootflash:c6msfc2-jsv-mz.121-8b.E11

Use the show module command to verify that the MSFC does, in fact, appear in the chassis.
