For optimum router performance, verify the condition of the host subsystem. The host
subsystem includes 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 (see Table 9 in
page 107).
Check the LEDs on the Routing Engine faceplate (see Table 10 in
Engine Description" on page
To check the status of the Routing Engines, issue the
command. The output is similar to the following:
