Type 4 or Type 5 PICs—To secure the PIC to the FPC faceplate, twist the ejector handle
4.
at the bottom of the PIC faceplate, then twist the ejector handle at the top of the
faceplate counterclockwise to unseat the PIC.
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 the PIC offline/online button until the status LED on the PIC lights green. For
a Type 4 or Type 5 PIC, use a narrow-ended tool that fits inside the opening that
leads to the button.
For more information about the PIC LEDs, see the
Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot online
The normal functioning status LED confirms that the PIC is online. You can also verify
correct PIC functioning by issuing the
