Juniper Networks EX4200 - Manual (Page 206)

To disconnect a fiber-optic cable from an optical transceiver installed in an EX Series
switch:
1. Disable the port in which the transceiver is installed by issuing the command:
[edit interfaces]
user@switch# set interface-name disable
WARNING: Do not look directly into a fiber-optic transceiver or into the ends of
fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to
transceivers emit laser light that can damage your eyes.
2. Carefully unplug the fiber-optic cable connector from the transceiver.
3. Cover the transceiver with a rubber safety cap.
WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing a cable. The rubber safety cap keeps the port clean and prevents
accidental exposure to laser light.
4. Cover the fiber-optic cable connector with the rubber safety cap.
