Install an FPC or Quad-wide PIC

To install an FPC or quad-wide PIC, follow this procedure (for brevity, the instructions refer to FPCs only):

1. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
2. Install or remove PICs as desired by following the instructions inReplace a PIC. You must install or remove PICs before installing the FPC into the chassis. If any PICs use fiber-optic cable, make sure that each transceiver is covered with a rubber safety cap.
3. Verify that the ends of the extractor clips are pointing outward toward the ends of the FPC.
4. Grasp the front of the FPC with both hands and align the rear with the guides at the sides of the FPC slot in the chassis.
5. Slide the FPC straight into the card cage until it contacts the backplane.  
   
   

   When about 1 in. (2.5 cm) of the FPC remains outside the slot, adjust the insertion speed so that it takes between 1 and 15 seconds for the FPC to contact the backplane. Completing the insertion too quickly or too slowly can cause the router to reset.

   
   
6. Push the ends of the extractor clips, located at each end of the FPC, inward toward the center of the FPC (see Figure 76).
7. Tighten the thumbscrew at each end of the FPC.
8. If any of the PICs on the FPC use fiber-optic cable, remove the rubber safety cap from each transceiver and the end of each cable. 
   
   

   Do not look directly into the ends of fiber-optic cables or into the transceivers on the PIC faceplate. Single-mode fiber-optic cable and the PICs that use it (such as ATM and SONET/SDH interfaces) emit laser light that can damage your eyes.

   
   
9. Insert the appropriate cables into the cable connector ports on each PIC on the FPC. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop, using the cable management system. Placing fasteners on a loop helps to maintain its shape. 
   
   

   Do not let cable hang free from the connector. Do not allow fastened loops of cable to dangle from the ladder rack, because this stresses the cable at the fastening point. Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

   
   
10. Press and hold the FPC offline button on the craft interface.

The green LED labeled OK blinks for about 5 seconds while the Routing Engine downloads the FPC software, the FPC runs its diagnostics, and the PICs housed in the FPC are enabled. Router forwarding operations then halt for about 200 ms while the Packet Forwarding Engine incorporates the memory on the new FPC into the memory buffers shared by all FPCs. When the FPC is online, the OK LED lights steadily and you can release the offline button.

You can also verify correct PIC and FPC functioning by issuing the show chassis fpc commands described in Maintain FPCs and PICs.

11. If you are installing multiple FPCs, repeat Steps 2 through 10 for each one. Wait 30 seconds after installing each FPC to allow the FPC and PICs to come online.
