Removing an MX480 SCB
To remove an SCB (see Figure 87 on page 175 ):
NOTE: You can remove the SCB and Routing Engine as a unit, or remove the
Routing Engine separately.
CAUTION: Before removing an SCB, ensure that you know how to operate
the ejector handles properly to avoid damage to the equipment.
CAUTION: Before you replace an SCB, you must take the host subsystem
offline. If there is only one host subsystem, taking the host subsystem offline
shuts down the router.
1. Take the host subsystem offline.
2. Place an electrostatic bag or antistatic mat on a flat, stable surface.
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
4. Rotate the ejector handles simultaneously counterclockwise to unseat the SCB.
5. Grasp the ejector handles, and slide the SCB about halfway out of the chassis.
6. Place one hand underneath the SCB to support it, and slide it completely out of the
chassis.
7. Place the SCB on the antistatic mat.
8. If you are not replacing the SCB now, install a blank panel over the empty slot.
