Installing an MX480 MPC
An MPC installs horizontally in the front of the router. The MPCs are hot-insertable and
hot-removable. A fully configured MPC can weigh up to 18.35 lb (8.3 kg). Be prepared to
accept its full weight.
To install an MPC (see Figure 127 on page 302 ):
1.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2.
Place the MPC on an antistatic mat.
3.
Take each MIC to be installed in the replacement MPC out of its electrostatic bag,
and identify the slot on the MPC where it will be connected.
4.
Verify that each fiber-optic MIC has a rubber safety cap covering the MIC transceiver.
If it does not, cover the transceiver with a safety cap.
5.
Install each MIC into the appropriate slot on the MPC.
6.
Locate the slot in the card cage in which you plan to install the MPC.
7.
Orient the MPC so that the faceplate faces you.
