8. Tighten the captive screws on the right and left ends of the Routing Engine faceplate.
9. Power on the services gateway. The OK LED on the power supply faceplate should blink, then light
steadily.
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. 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

10. If the Routing Engine was replaced on one of the nodes in a chassis cluster, then you need to copy
certificates and key pairs from the other node in the cluster:
a. Start the shell interface as a root user on both nodes of the cluster.
b. Verify files in the /var/db/certs/common/key-pair folder of the source node (other node in the
cluster) and destination node (node on which the Routing Engine was replaced) by using the following
command:
ls -la /var/db/certs/common/key-pair/
c. If the same files exist on both nodes, back up the files on the destination node to a different location.
For example:
root@SRX-B% pwd
/var/db/certs/common/key-pair
root@SRX-B% ls -la
