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.
3. Insert the cable connector into the cable connector port on the PIC faceplate.
4. Arrange the cable in the cable management system, to prevent it from 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: 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.
5. Insert the other end of the cable into the destination port.
6. Repeat the previous steps for any additional cables.
7. If the PIC is offline (its failure indicator LED is lit), use one of the following methods to bring the PIC
online:
• Press the PIC offline/online button until the PIC LED lights green.
• Issue the following CLI command:
