CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius.An arc smaller than a few inches in diametercan damage the cable
and cause problems that are difficult to diagnose.
7. Unseat the PIC: Flip the ejector handles outward.
8. Slide the PIC out of the FPC card carrier, and place it in the electrostatic bag or on the
antistatic mat.
9. 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.
Installing a PTX5000 PIC
To install a PIC:
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
2. Verify that there is a rubber safety cap over each fiber-optic transceiver on the
faceplate. Install a cap if necessary.
3. Align the notches in the connector at the rear of the PIC with the notches in the PIC
slot in the FPC and then slide the PIC in until it lodges firmly in the FPC.
CAUTION: Slide the PIC straight into the slot to avoid damaging the
components on the bottom of the PIC.
4. Secure the PIC to the FPC faceplate: Grasp both ejector handles and press them
inward to seat the PIC until the ejectors latch into the FPC.
5. Remove the rubber safety cap from each fiber-optic transceiver and the end of each
fiber-optic cable.
WARNING: 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 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.
6. Insert the appropriate cables into the cable connectors on the PIC.
7. Arrange each cable in the cable management system to prevent the cable 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
