CAUTION: Do not leave a fiber-optic transceiver uncovered except when
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
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.
CAUTION: 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.
6.
Simultaneously turn both of the ejector handles counterclockwise to unseat the SPC.
7.
Grasp the handles and slide the SPC straight out of the card cage halfway.
8.
Place one hand around the front of the SPC and the other hand under it to support it.
Slide the SPC completely out of the chassis, and place it on the antistatic mat or in
the electrostatic bag.
CAUTION: The weight of the SPC is concentrated in the back end. Be
prepared to accept the full weight—up to 18.3 lb (8.3 kg)—as you slide the
SPC out of the chassis.
When the SPC 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 SPCs 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.
9.
If you are not reinstalling an SPC into the empty slot within a short time, install a blank
panel over the slot to maintain proper airflow in the card cage.
