Removing an MX480 AS MXC
AS MXCs are hot-insertable and hot-removable. When you remove an AS MXC,the router
continues to function.
The AS MXCs are located in the AS MLCs installed in the front of the router. An AS MXC
weighs 1.4 lb (0.6 kg).
To remove an AS MXC (see Figure 157 on page 364):
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the AS
MXC.
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 MXC 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 MXC 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.
5. Slide the AS MXC out of the AS MLC card carrier by pulling the handles, and place it
in the electrostatic bag or on the antistatic mat.
6. If you are not reinstalling an AS MXC into the emptied AS MXC slot within a short time,
install a blank AS MXC panel over the slot to maintain proper airflow in the AS MLC
card cage.
