Replace an FPC in an M40 Router

4.Take the FPC offline by pressing and holding its offline button for 5 seconds or until the green OK LED next to the button goes out. The offline button for each FPC is located on the craft interface just below the FPC slot.

5.Disconnect the cables from the PICs on the FPC. If a PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap. Arrange the disconnected cables in the cable management system at the top of the chassis front, to prevent the cables from developing stress points.

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.

Do not leave a transceiver uncovered. The safety cap keeps the port clean and prevents accidental exposure to laser light.

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.

6.Unscrew the thumbscrews at the top and bottom of the FPC.

7.Pull the ends of the extractor clips, which are adjacent to the thumbscrews, away from the face of the FPC. See Figure 9.

8.Grasp the FPC with both hands and slide it about halfway out of the chassis.

9.Place one hand underneath the FPC to support it, and slide it completely out of the chassis. Set the FPC on the antistatic foam mat prepared in Step 1, component-side down and with the PIC faceplates facing you.

To avoid damaging any components, use extra care when laying the FPC component-side down on the antistatic mat, particularly if the mat is not made of foam.

Do not stack the FPC on top of or under any other component.

10.If you are removing or replacing PICs on the FPC, see the instructions in the M40 Internet Router Hardware Guide.
