Replace PIC Cables
Removing and installing PIC cables does not affect router function, except that the PIC does
not receive or transmit data while the cable is disconnected. To replace a PIC cable, perform
the following procedures:

Remove a PIC Cable
To remove a PIC cable, follow this procedure:
1.
If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each cable you
are removing and the transceiver into which it plugs.

2.
Unplug the cable from the cable connector port and immediately place a rubber safety
cap over the port if it connects to fiber-optic cable.

3.
Carefully thread the cable through the cable management system, to prevent the cable
from dislodging or developing stress points. 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.

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.

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.
