Removing an MX480 SCB
To remove an SCB (see Figure 165 on page 382):
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.
