Disconnect A Fiber-Optic Cable - Juniper EX9214 Hardware Manual

4. Secure the cables so that they do not support their own weight. Place excess cable 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. An arc
smaller than a few inches in diameter can damage the cables and cause problems that
are difficult to diagnose.
Do not let fiber-optic cables hang free from the connector. Do not allow fastened
loops of cables to dangle, which stresses the cables at the fastening point.

Disconnect a Fiber-Optic Cable

Before you disconnect a fiber-optic cable from an optical transceiver, ensure that you have taken the
necessary precautions for safe handling of lasers. See
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
Juniper Networks devices have optical transceivers to which you can connect fiber-optic cables.
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]
interface-name disable
user@device# set
LASER 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.
