Removing an MX240 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 116 on page 338
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).
