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
Before you begin to connect a fiber-optic cable to an optical transceiver installed in a device, ensure that
you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines
and Warnings” on page 220 ).
