MX240 Ethernet Services Router Hardware Guide

Maintaining the Host Subsystem

The host subsystem comprises an SCB and a Routing Engine installed into a slot in the SCB. To maintain the host subsystem components, follow these guidelines:

Check the LEDs on the craft interface to view information about the status of the Routing Engines. For more information about the LEDs, see “Craft Interface” on page 17.

Check the LEDs on the SCB faceplate (see Table 9 on page 13).

Check the LEDs on the Routing Engine faceplate (see Table 10 on page 16).

To check the status of the Routing Engines, issue the show chassis routing-enginecommand. The output is similar to the following:

user@host> show chassis routing-engine
