Juniper QFabric QFX3008-I, Manual, Page: 403 / 472

To disconnect a fiber-optic cable from an optical transceiver installed in a QFX Series
device:
1.
(Recommended) Disable the port in which the transceiver is installed by including
the
disable
statement at the
[edit interfaces]
hierarchy level for the specific interface.
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.
WARNING: Do not stare into the laser beam or view it directly with optical
instruments even if the interface has been disabled.
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.
