Figure 87: Removing an SCB
Installing an MX480 SCB
To install an SCB (see Figure 88 on page 176 ):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
2. Carefully align the sides of the SCB with the guides inside the chassis.
3. Slide the SCB into the chassis until you feel resistance, carefully ensuring that it is
correctly aligned.
4. Grasp both ejector handles, and rotate them simultaneously clockwise until the SCB
is fully seated.
5. Place the ejector handles in the proper position, horizontally and toward the center
of the board.
6. Check the LEDs on the SCB faceplate to verify that it is functioning normally.
• 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.
7. Check the status of the SCB using the show chassis environment cb command:
user@host> show chassis environment cb
