and prevents accidental exposure to laser light.
Cover the fiber-optic cable connector with the rubber safety cap.

The QFX Series has field-replaceable unit (FRU) optical transceivers to which you can
connect fiber-optic cables. You can remove and replace the cables without powering
off the device or disrupting the switching functions.
Before you connect a fiber-optic cable to 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
To connect a fiber-optic cable to an optical transceiver installed in the QFX Series:
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.
If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap.

cap.
Insert the cable connector into the optical transceiver.

out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain
their shape.
CAUTION: Do not bend fiber-optic cables beyond their minimum bend
radius. Bending the cables beyond their minimum bend radius can damage
the cables and cause problems that are difficult to diagnose.
