Replace an FPC in an M40e or M160 Router

4.Grasp the front of the FPC with one hand and place the other hand under the FPC to support it.

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

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

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 12, which shows an M160 router).

7.If installing an M40e-FPC1 or M40e-FPC2 in an M40e router or any FPC in an

M160 router, you can remove or replace PICs at this point. For instructions, see the M40e Internet Router Hardware Guide or M160 Internet Router Hardware Guide.

8.If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety cap from each transceiver and 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 cable 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 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.
