Maintaining the MX480 Host Subsystem
Purpose
For optimum router performance, verify the condition of the host subsystem. The host
subsystem comprises an SCB and a Routing Engine installed directly into an SCB.
Action
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
show chassis routing-engine
command. The output is similar to the following:
