Ensure that you have the following parts and tools available:
•
A rubber safety cap to cover the transceiver
•
A rubber safety cap to cover the fiber-optic cable connector
To disconnect a fiber-optic cable from an optical transceiver installed in the device:
1. Disable the port in which the transceiver is installed by issuing the following command:
[edit interfaces]
user@device#
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.
Connecting a Fiber-Optic Cable to a QFX Series Device
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 212 ).
