Removing a PIC
The PICs are located in the FPCs installed in the front of the router.
A PIC weighs less than 2 lb (0.9 kg).
To remove a PIC (see Figure 7):
an electrostatic bag or antistatic mat on a flat, stable surface to receive
the PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety
cap for each transceiver and cable.
- Attach an electrostatic discharge (ESD) grounding strap to your bare
wrist and connect the strap to one of the ESD points on the chassis.
- Use one of the following methods to take the PIC offline:
- Label the cables connected to the PIC so that you can later
reconnect each cable to the correct PIC.
the cables from the PIC. If the PIC uses fiber-optic cable, immediately cover
each transceiver and the end of each cable with a rubber safety cap.
Do not look directly into a fiber-optic transceiver or into
the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic
cable connected to a transceiver emit laser light that can damage
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.
- 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.
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.
an FPC3 PIC, loosen the captive screw at the bottom of the PIC faceplate,
and then twist the ejector handle at the top of the faceplate counterclockwise
to unseat the PIC. For an FPC1 or FPC2 PIC, loosen the captive screws
at the top and bottom of the faceplate.
the PIC out of the FPC card carrier and place it in the electrostatic bag
or on the antistatic mat.
- If you are not reinstalling a PIC into the emptied PIC
slot within a short time, install a blank PIC panel over the slot to maintain
proper airflow in the FPC card cage.
