If you install only one Routing Engine in the services gateway, you must install it in the slot in the front panel of SCB0. If you install a second routing engine to use the dual chassis cluster control link feature, you install it in the slot in the front panel of SCB1.
To install a Routing Engine into an SCB (see Figure 1):
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-engineRouting Engine status:
Slot 0:
Current state Master ... For more information about using the CLI, see the Junos OS manuals.
