that use it (such as ATM and SONET/SDH interfaces) 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.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.

7.Unseat the PIC from the chassis:

■For a regular PIC, pull the right end of the PIC ejector lever away from the PIC faceplate.

■For a quad-wide PIC, pull the end of each ejector lever away from the PIC faceplate, toward the outer edges of the PIC.

8.Grasp both sides of the PIC faceplate and slide it out of the chassis. Do not use the ejector lever as a handle.

9.Place the PIC in the electrostatic bag or on the antistatic mat.

10.If you are not reinstalling a PIC into the emptied slot within a short time, install a blank PIC panel over the slot to maintain proper airflow in the chassis.
