Removing an MX104 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 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 48 on page 163):
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 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 five seconds).
•
Issue the following CLI command:
user@host> request chassis mic fpc-slot slot-number mic-slot slot-number offline
