Installing an M40e FPC

To install an FPC into an M40e router, 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. If you are installing an M40e-FPC, you can remove or replace PICs now, before installing the M40e-FPC into the chassis. See the PIC and Transceiver Installation Instructions.

   If you are installing an M40e FPC1 or M40e FPC2 into an M40e router, wait to remove or replace PICs until Step  7.

   If any PIC uses fiber-optic cable, make sure that each transceiver is covered with a rubber safety cap.

3. Verify that the ends of the ejector levers, which are at the top and bottom of the FPC, are pushed outward and nearly perpendicular to the face of the FPC.
4. Grasp the front of the FPC with one hand, and place the other hand under the FPC to support it.

   Caution: Do not hold the FPC by the ejector levers, bus bars, or edge connectors. They cannot support its weight.

5. Align the bottom rear corner of the FPC with the guide at the bottom of the desired FPC slot. Slide the FPC all the way into the card cage until it contacts the midplane.

   Note: When an M40e FPC is installed in the chassis, the lettering on the faceplates of the PICs is upside down.

6. Push the ends of the ejector levers inward until they are nearly flush with the face of the FPC (see Figure 11).
7. If you are installing an M40e FPC1 or M40e FPC2 into an M40e router, you can remove or replace PICs at this point. For instructions, see the PIC and Transceiver Installation Instructions.
8. If any PICs on the FPC connect to fiber-optic cable, remove the rubber safety 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.

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

   Caution: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

   Caution: 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 above the slot that houses the FPC) to bring the FPC and PICs online. When the FPC is online, the FPC LED labeled OK on the craft interface lights steadily, and you can release the offline button.
