3.
Disconnect the cable from the cable connector port. If the component uses fiber-optic
cable, immediately cover each transceiver and the end of each cable with a rubber
safety cap.
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
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
4.
Remove the cable from the cable management brackets.
5.
Disconnect the cable from the destination port.
