WARNING:
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to a transceiver emit laser light that can damage your eyes.
CAUTION:
inserting or removing a cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
CAUTION:
An arc smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
6. Arrange the disconnected cables in the cable manager to prevent the cables from developing stress
points.
7. Simultaneously turn both the ejector handles counterclockwise to unseat the MX-SPC3.
8. Grasp the handles, and slide the MX-SPC3 straight out of the card cage halfway.
9. Place one hand around the front of the MX-SPC3 and the other hand under it to support it. Slide the
MX-SPC3 completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.
CAUTION:
prepared to accept the full weight—up to 18.35 lb (8.3 kg)—as you slide the
MX-SPC3 out of the chassis.
When the MX-SPC3 is out of the chassis, do not hold it by the ejector handles,
bus bars, or edge connectors. They cannot support its weight.
Do not stack MX-SPC3s on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a flat, stable
surface.
10. If you are not reinstalling an MX-SPC3 into the emptied line card slots within a short time, install a
blank panel over each slot to maintain proper airflow in the card cage.
Do not look directly into a fiber-optic transceiver or into the ends
Do not leave a fiber-optic transceiver uncovered except when
