Disconnecting a Fiber-Optic Cable from an ACX5000 Router
The ACX routers has field-replaceable unit (FRU) optical transceivers to which you can connect fiber-optic
cables.
Before you disconnect a fiber-optic cable from an optical transceiver installed in an ACX router, ensure
that you have taken the necessary precautions for safe handling of lasers (see
“Laser and LED Safety
Guidelines and Warnings for the ACX5000 Router” on page 178 ).
Ensure that you have the following parts and tools available:
•
Rubber safety cap to cover the transceiver
•
Rubber safety cap to cover the fiber-optic cable connector
To disconnect a fiber-optic cable from an optical transceiver installed in an ACX5000 router:
1. (Recommended) Disable the port in which the transceiver is installed by including the disable statement
at the [edit interfaces] hierarchy level for the specific interface.
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.
WARNING: Do not stare into the laser beam or view it directly with optical
instruments even if the interface has been disabled.
2. Carefully unplug the fiber-optic cable connector from the transceiver.
