DETAILED STEPS
Troubleshooting Blocked FCC Shelf Controller or LCC Route Process Minimum
Boot Image Requests
Note This procedure applies to Cisco CRS-1 Multishelf Systems only.
To troubleshoot blocked fabric card chassis SC or line card chassis RP minimum boot image (MBI)
requests, perform the following procedures.
If the shelf controller (SC) or route processor (RP) in the remote line card chassis fails to boot correctly,
messages are displayed on the console of either device, indicating that it is waiting for information from
the designated shelf controller (DSC).
Command or Action Purpose
Step 1
Place both RPs in ROMMON mode. See Router Recovery with ROM Monitor mode. See the

Displays the environment variable settings for the card.
Verify that the variables are valid.
Step 3
For each affected chassis, verify that all three LEDs on
power modules are green.
See Cisco CRS-1 Carrier Routing System 16-Slot Line Card
Chassis Hardware Operations and Troubleshooting Guide
for the location of the power modules.
Step 4
Power cycle the power modules to confirm that the
LEDs transition from amber to green.
If the LEDs on the power modules stay amber or go from
amber to green then back to amber, there is a problem with
the power module.
