CAUTION:
An arc smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
7. Immediately cover each optical transceiver and the end of each fiber-optic cable with a rubber safety
cap.
8. Cover the ports on the IOC with dust covers if you remove the optical transceivers from the IOC.
9. Arrange the disconnected cables in the cable manager to prevent the cables from developing stress
points.
10. Simultaneously turn both of the ejector handles counterclockwise to unseat the IOC.
11. Grasp the handles and slide the IOC straight out of the card cage halfway.
12. Place one hand around the front of the IOC and the other hand under it to support it. Slide the IOC
completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.
CAUTION:
to accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the IOC out of the
chassis.
When the IOC 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 IOC 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.
13. If you are not reinstalling an IOC into the empy slot within a short time, install a blank IOC panel over
the slot to maintain proper airflow in the card cage.
CAUTION:
before reinserting it, removing an IOC from a different slot, or inserting an IOC
into a different slot.
Avoid bending a fiber-optic cable beyond its minimum bend radius.
The weight of the IOC is concentrated in the back end. Be prepared
After removing an IOC from the chassis, wait at least 30 seconds
