The Routing Engine might require several minutes to boot.
After the Routing Engine boots, verify that it is installed
correctly by checking the RE0 and RE1 LEDs on the
craft interface. If the services gateway is operational and the Routing
Engine is functioning properly, the green ONLINE LED lights
steadily. If the red FAIL LED lights steadily instead, remove
and install the Routing Engine again (see Removing a Routing Engine and Installing a Routing Engine). If the red FAIL LED still lights steadily, the Routing Engine is not functioning
properly. Contact your customer support representative.
To check the status of the Routing Engine, use the CLI command:
user@host> show chassis routing-engine
Routing Engine status: Slot 0: Current state Master ...
For more information about using the CLI, see the JUNOS software
