Figure 96: Removing a DPC
Installing an MX480 DPC
A DPC weighs up to 14.5 lb (6.6 kg). Be prepared to accept its full weight.
To install a DPC (see Figure 97 on page 193 ):
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 DPC on an antistatic mat, or remove it from its electrostatic bag.
3. Identify the slot on the router where it will be installed.
4. Verify that each fiber-optic transceiver is covered with a rubber safety cap. If it does
not, cover the transceiver with a safety cap.
5. Orient the DPC so that the faceplate faces you.
6. Lift the DPC into place, and carefully align the sides of the DPC with the guides inside
the card cage.
7. Slide the DPC all the way into the card cage until you feel resistance.
8. Grasp both ejector handles, and rotate them clockwise simultaneously until the DPC
is fully seated.
9. Remove the rubber safety cap from each fiber-optic transceiver and cable.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
10. Insert the cables into the cable connector ports on each DPC (see Figure 98 on
page 194 ).
11. Arrange the cable in the cable management brackets to prevent it from dislodging or
developing stress points. Secure the cable so that it is not supporting its own weight
