Disconnecting a Fiber-Optic Cable
ACX Series routers have field-replaceable unit (FRU) optical transceivers to which you can connect fiber-
optic cables.
Before you begin disconnecting a fiber-optic cable from an optical transceiver installed in an ACX Series
router, ensure that you have taken the necessary precautions for safe handling of lasers (see
Laser Safety Guidelines for Juniper Networks Devices
).
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 router:
1. Disable the port in which the transceiver is installed by issuing the following command:
[edit interfaces]
user@router# set
interface-name disable
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.
