Install a PIC Cable
1.
Have ready a length of the type of cable used by the PIC, as specified in the M20 and
M40 Internet Routers PIC Guide. Figure 86 depicts the connector on fiber-optic cable.

2.
Remove the rubber safety plug from the PIC cable connector port.
3.
Insert the cable connector into the cable connector port on the PIC faceplate (see
Figure 87, which shows a fiber-optic connector).

4.
Carefully thread the cable through in the cable management system, to prevent the
cable from dislodging or developing stress points. Secure the cable so that it is not
supporting its own weight as it hangs from the connector. 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.

5.
Verify that the PIC is functioning correctly by noting whether the normal function
indicator LED is lit. The normal function indicator LED is usually green; for more
information, see the M20 and M40 Internet Routers PIC Guide.

information, see the M20 and M40 Internet Routers PIC Guide.
You can also verify correct PIC functioning by issuing the
show chassis fpc pic-status
command, described in “Maintain FPCs and PICs” on page 162.
Do not look directly into the ends of fiber-optic cables or
the transceivers on the faceplate of a PIC that connects to
fiber-optic cable. Single-mode fiber-optic cable and the
PICs that use it (such as ATM and SONET/SDH) emit laser
light that can damage your eyes.

Do not leave a transceiver uncovered except when
removing or inserting the cable. 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.

Never 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.
