Removing An Mx480 Mic - Juniper MX480 Hardware Manual

Removing an MX480 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.
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 123 on page 354
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. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end of the strap to the ESD point on the chassis.
3. 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 OK/FAIL LED goes off (about 5 seconds).

user@host> request chassis mic fpc-slot mpc-slot mic-slot mic-slot offline

4. Label the cables connected to the MIC so that you can later reconnect each cable to the correct MIC.

and the end of each cable with a rubber safety cap.

of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to a transceiver emit laser light that can damage your eyes.
CAUTION:
are inserting or removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
6. 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.
