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 MX104 router, the MICs can be installed in four slots in the front of the router. A
MIC weighs less than 2 lb (0.9 kg).
To remove a MIC (see Figure 31 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 ESD grounding strap to your bare wrist and connect the strap to one of the
2.
ESD points on the chassis.
Use one of the following methods to take the MIC offline:
3.
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 five seconds).
Issue the following CLI command:
user@host> request chassis mic fpc-slot slot-number mic-slot slot-number offline
Label the cables connected to the MIC so that you can later reconnect each cable to
4.
the correct MIC.
Disconnect the cables from the MIC. If the MIC uses a fiber-optic cable, immediately
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
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
Arrange the cable to prevent it from dislodging or developing stress points. Secure

the cable so that it is not supporting its own weight as it hangs to the floor. Place
excess cable out of the way in a neatly coiled loop.
