Removing an MX2010 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 272 on page 517 ):
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 electrostatic discharge (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 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).
•
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 Junos OS System Basics and Services Command
Reference .
4. Label the cables connected to the MIC so that you can later reconnect each cable to the correct MIC.
