Juniper SRX 5800, Hardware Manual, Page: 309 / 536

1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
2. Power off the services gateway using the command request system power-off.
user@host#
request system power-off
NOTE: Wait until a message appears on the console confirming that the services stopped.
3. Physically turn off the power and remove the power cables from the chassis.
4. Carefully align the sides of the SCB with the guides inside the chassis.
5. Slide the SCB into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
6. Grasp both ejector handles and rotate them simultaneously clockwise until the SCB is fully seated.
7. Place the ejector handles in the proper position, vertically and toward the center of the board.
8. Connect the power cables to the chassis and power on the services gateway.
9. To verify that the SCB is functioning normally, check the LEDs on its faceplate. The green OK/FAIL
LED should light steadily a few minutes after the SCB is installed. If the OK/FAIL LED is red, remove
and install the SCB again. If the OK/FAIL LED still lights steadily, the SCB is not functioning properly.
Contact your customer support representative.
To check the status of the SCB:

10. If you installed an SCB into a chassis cluster, through the console of the newly installed SCB put the
node back into cluster and reboot.
user@host>

where x is the cluster ID and Y is the node ID
11. Activate the disabled fabric interfaces.
