Removing an ACX4000 MIC
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.
In the ACX4000 router, the MICs can be installed in two slots in the front of the router. A MIC weighs
less than 2 lb (0.9 kg).
To remove a MIC (see Figure
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the MIC. If the MIC
connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.
2. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD
grounding point.
3. Take the MIC offline by issuing the following CLI command:
user@host> request chassis mic fpc-slot slot-number mic-slot slot-number offline
4. Label the cables connected to the MIC so that you can later reconnect each cable to the correct
MIC.
5. Disconnect the cables from the MIC. If the MIC uses fiber-optic cable, immediately cover each
transceiver and the end of each cable with a rubber safety cap.
LASER WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a
transceiver emit laser light that can damage your eyes.
