Removing an MX480 AS MSC
ASMSCs 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 155 on page 361):
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the AS
MSC.
2. Attach an 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).
•
Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
For more information about the command, see the CLI Explorer.
4. Slide the AS MSC out of the AS MLC card carrier by pulling the handles, and place it
in the electrostatic bag or on the antistatic mat.
5. If you are not reinstalling an AS MSC into the emptied AS MSC slot within a short time,
install a blank AS MSC panel over the slot to maintain proper airflow in the AS MLC
card cage.
