Replacing an MX480 AS MSC
1. Removing an MX480 AS MSC on page 217
2. Installing an MX480 AS MSC on page 218
Removing an MX480 AS MSC
AS MSCs are hot-insertable and hot-removable. When you remove an AS MSC, the router
continues to function.
The AS MSCs are located in the AS MLCs installed in the front of the router. An AS MSC
weighs 1.4 lb (0.6 kg).
To remove an AS MSC (see Figure 113 on page 218 ):
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the AS
MSC.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
3. Use one of the following methods to take the AS MSC offline:
• Press its online/offline button. Use a narrow-ended tool that fits inside the opening
that leads to the button. Press and hold the button until the AS MSC LED goes out
(about 5 seconds).
