Chapter 13: Removing Switch Components To disconnect a fiber-optic cable from an optical transceiver installed in the switch: 1. Disable the port in which the transceiver is installed by issuing the command: [edit interfaces] user@switch# 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.
