Juniper QFX5100, Hardware Manual

Page: 227 / 256

Before you disconnect a fiber-optic cable from an optical transceiver installed in the QFX
Series, ensure that you have taken the necessary precautions for safe handling of lasers
(see
“Laser and LED Safety Guidelines and Warnings for the QFX Series” on page 120 ).
Ensure that you have the following parts and tools available:
•
Rubber safety cap to cover the transceiver
• Rubber safety cap to cover the fiber-optic cable connector
To disconnect a fiber-optic cable from an optical transceiver installed in the QFX Series:
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.
