When the MPC is out of the chassis, do not hold it by the ejector handles,
bus bars, or edge connectors. They cannot support its weight.
Do not stack MPCs on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a flat,
stable surface.
10. If necessary, remove each installed MIC from the MPC.
11. After you remove each MIC, immediately place it on an antistatic mat or in an
electrostatic bag.
12. If you are not reinstalling an MPC into the emptied line card slots within a short time,
install a blank DPC panel over each slot to maintain proper airflow in the card cage.
CAUTION: After removing an MPC from the chassis, wait at least 30
seconds before reinserting it or inserting an MPC into a different slot.

MPC
Installing an MX240 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 97 on page 244):
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.
