For optimum router performance, verify the condition of the host subsystem. The host
subsystem comprises an SCB and a Routing Engine installed into a slot in the SCB.
On a regular basis:
Check the LEDs on the craft interface to view information about the status of the
Routing Engines.
Check the LEDs on the SCB faceplate.
Check the LEDs on the Routing Engine faceplate.
To check the status of the Routing Engines, issue the
command. The output is similar to the following:
