For an FPC3 PIC, turn the ejector handle at the top of the PIC faceplate clockwise,
4.
and then tighten the captive screw at the bottom of the faceplate to secure the PIC
in the FPC. For an FPC 1 or FPC2 PIC, tighten the captive screws at the top and bottom
of the faceplate.
If the PIC uses fiber-optic cable, remove the rubber safety cap from each transceiver
5.
and the end of each 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.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
Insert the appropriate cables into the cable connectors on the PIC.
6.
Arrange each cable in the cable management system to prevent the cable from
7.
dislodging or developing stress points. Secure the cable so that it is not supporting its
own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled
loop in the cable management system. Placing fasteners on the 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.
Use one of the following methods to bring the PIC online:
8.
Press and hold the PIC offline button until the status LED on the PIC faceplate
indicates normal functioning, which usually takes about 5 seconds. The LED is
usually green; for more information, see the M120 Multiservice Edge Router Interface
Module Reference. For the PICs that install on an FPC1, the offline button for each
PIC is next to it on the FPC card carrier. For the PICs that install on an FPC2 or FPC3,
the offline button is on the PIC faceplate.
Issue the CLI command:
