Remove the FPCs

The router can have up to eight FPCs mounted vertically in the FPC card cage at the front of the chassis (see Figure 1). An FPC that houses four PICs weighs about 3 lb (1.5 kg). 

To help you work systematically, the following procedure directs you to remove FPCs starting at the left side of the card cage and working toward the right. You can remove FPCs in any order, however. As you remove each FPC, label it with its slot number and record the relevant information in the checklist in Table 21.

To remove the FPCs, follow this procedure:

1. Place an antistatic mat or electrostatic bag on a flat, stable surface to receive each FPC.
2. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
3. Locate the FPC or blank panel located in the leftmost slot of the card cage on the front of the chassis. It is directly above the offline button on the craft interface that is labeled 0 (zero).
4. If the slot is covered by a blank panel, you can leave it in place. If the slot contains an FPC, perform the following steps:

1. Loosen the thumbscrew at each end of the FPC, using a Phillips screwdriver if necessary.
2. Pull the ends of the extractor clips, which are adjacent to the thumbscrews, toward the outer edges of the FPC (see Figure 32).
3. Grasp both sides of the card carrier and slide the FPC about halfway out of the card cage.
4. Place one hand under the FPC to support it, slide it completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag prepared in Step 1.  
   
   

   Do not stack FPCs on top of one another (or any other components) after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

   
   

5. Repeat Step 4 for each FPC card carrier or blank cover, proceeding from left to right.
