Have ready a length of the type of cable used by the PIC. For cable specifications,
1.
see the M10i Internet Router PIC Guide.
If the PIC cable connector port is covered by a rubber safety plug, remove the
2.
plug.
WARNING: Do not look directly into the ends of fiber-optic cables or into the
transceivers on the interface faceplate. Single-mode fiber-optic cable and the interfaces
that use it (such as ATM and SONET/SDH interfaces) 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 cable connector into the cable connector port on the PIC faceplate.
3.
Arrange the cable in the cable management system to prevent it from dislodging
4.
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: 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.
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.
Insert the other end of the cable into the destination port.
