Reinstall the FPCs

The FPCs install into the card cage at the front of the chassis, as shown in Figure 1.

To help you work systematically, the following procedure directs you to reinstall FPCs starting at the left side of the card cage and working toward the right. You can install FPCs in any order, however. Be sure there is a blank panel over every empty slot. The blank panels must be in place during router operation to guarantee adequate circulation of cooling air.

To reinstall the FPCs, follow this procedure:

1. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
2. Locate the leftmost slot in the FPC card cage on the front of the chassis. It is directly above the offline button on the craft interface that is labeled 0 (zero).
3. Locate the FPC that you labeled 0 during removal. Verify that the ends of the extractor clips, which are located at each end of the FPC, are pushed outward, toward the ends of the FPC.
4. Grasp the front of the FPC with both hands and align the rear of the card carrier with the slide guides in the card cage.
5. Slide the FPC all the way into the card cage until it contacts the backplane.
6. Push the ends of the extractor clips toward each other to secure the FPC in the chassis.
7. Using a Phillips screwdriver, tighten the thumbscrew at each end of the FPC to seat the unit firmly in the chassis.
8. Repeat Steps 4 through 7 for each FPC, proceeding from left to right through the remaining FPC slots.
