Figure 71: Reinstalling a DPC
Reinstalling the FPCs After Installing the MX240 Router without a Lift
To reinstall a DPC (see Figure 72 on page 195):
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. Place the FPC on an antistatic mat or remove it from its electrostatic bag.
3. Identify the two DPC slots on the router where the FPC will be installed.
4. Verify that each fiber-optic transceiver on the PIC is covered by a rubber safety cap.
If it does not, cover the transceiver with a safety cap.
5. Orient the FPC so that the faceplate faces you.
6. Lift the FPC into place and carefully align the sides of the FPC with the guides inside
the card cage.
7. Slide the FPC all the way into the card cage until you feel resistance.
8. Grasp both ejector handles and rotate them clockwise simultaneously until the FPC
is fully seated.
