CAUTION: Do not leave a fiber-optict ransceiveruncovered except when inserting
or removing cable. The safety cap keeps the port clean and preventsaccidental
exposure to laser light.
4. Remove the cable fromthe cable management system and detach it from
the destination port.
Installing a PIC Cable
To installa PIC cable, follow this procedure (see Figure 95):
1. Have ready a length of the type of cable used by the PIC. For cable
specifications, see the M160 Internet Router PIC Guide.
2. If the PIC cable connector port iscovered by a rubber safety plug, remove
the plug.
WARNING: Do not look directly into the ends of fiber-optic cables or into the
transceiverson the interface faceplate. Single-mode fiber-optic cableand the
interfaces that use it (such as ATMand SONET/SDH interfaces) emit laser light
that can damage your eyes.
CAUTION: Do not leave a fiber-optict ransceiveruncovered except when inserting
or removing cable. The safety cap keeps the port clean and preventsaccidental
exposure to laser light.
3. Insert the cable connectorinto the cable connector port on the PIC faceplate.
4. Arrange the cable in the cablemanagement system to prevent it from
dislodging or developing stress points. Secure the cable so that it is not
supporting its own weightas 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 indiameter can damage the cable and cause problems
that are difficult to diagnose.
