Before you begin to disconnect a fiber-optic cable from an optical transceiver, ensure that you have taken
the necessary precautions for safe handling of lasers. See “Laser and LED Safety Guidelines and Warnings”
on page 164 .
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.
