Installing an MX2020 MPC into an Adapter Card
An MPC weighs up to 25 lb (11.34 kg). Be prepared to accept its full weight.
To install an MPC (see Figure 239 on page 545):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
2. Remove the MPC from its electrostatic bag.
3. Identify the slot on the router where it will be installed.
4. Verify that each fiber-optic MPC has a rubber safety cap covering the transceiver. If it does not, cover
the transceiver with a safety cap.
5. Locate the slot in the ADC in which you plan to install the MPC.
6. Ensure that the MPC is right-side up, with the text on the faceplate facing upward.
7. Lift the MPC into place, and carefully align first the bottom, then the top of the MPC with the guides
inside the ADC.
8. Slide the MPC all the way into the ADC until you feel resistance.
