Installing an MX480 FPC

Copyright © 2011, Juniper Networks, Inc.
An FPC takes up two DPC slots on the MX480 router. Up to three FPCs can be installed
horizontally in the front of the router. The FPCs are hot-insertable and hot-removable.
An empty FPC3 weighs 14 lb (6.5 kg). A fully configured FPC can weigh up to 18 lb (8.2 kg).
Be prepared to accept its full weight.
To install an FPC (see Figure 96 on page
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
1.
the strap to one of the ESD points on the chassis.
Place the FPC on an antistatic mat.
2.
Take each PIC to be installed in the replacement FPC out of its electrostatic bag, and
3.
identify the slot on the FPC where it will be connected.
Verify that each fiber-optic PIC has a rubber safety cap covering the PIC transceiver.
4.
If it does not, cover the transceiver with a safety cap.
Install each PIC into the appropriate slot on the FPC.
5.
Locate the slots in the card cage in which you plan to install the FPC.
6.
Orient the FPC so that the faceplate faces you.
7.
Lift the FPC into place, and carefully align the sides of the FPC with the guides inside
8.
the card cage.
CAUTION: When the FPC is out of the chassis, do not hold it by the ejector
handles, bus bars, or edge connectors. They cannot support its weight.
Slide the FPC all the way into the card cage until you feel resistance.
9.
Grasp both ejector handles, and rotate them clockwise simultaneously until the FPC
10.
is fully seated.
If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety
11.
cap from each 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.
Insert the appropriate cable into the cable connector ports on each PIC on the FPC.
12.
Arrange the cable in the cable management brackets to prevent it from dislodging or
13.
developing stress points. Secure the cable so that it is not supporting its own weight
as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop.
Placing fasteners on the loop helps to maintain its shape.
