MICs are hot-insertable and hot-removable. When you remove a MIC, the router continues
to function, although the MIC interfaces being removed no longer function.
The MICs are located in the MPCs installed in the front of the router. A MIC weighs less
than 2 lb (0.9 kg).
To remove a MIC (see Figure 226 on page
Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
1.
MIC. If the MIC connects to fiber-optic cable, have ready a rubber safety cap for each
transceiver and cable.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the strap to one of the ESD points on the chassis.
Use one of the following methods to take the MIC 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 MIC
off (about 5 seconds).
Issue the following CLI command:
user@host> request chassis mic fpc-slot fpc-slot mic-slot mic-slot offline
For more information about the command, see the
Services Command Reference
Label the cables connected to the MIC so that you can later reconnect each cable to

5.
cover each transceiver and the end of each cable with a rubber safety cap.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
