Juniper Networks EX8208 manual Disconnecting a Fiber-Optic Cable from an EX Series Switch

Chapter 13: Removing Switch Components

CAUTION: After removing a line card, wait for at least 30 seconds before installing a line card or removing another line card.

9.If you are not installing a line card in the emptied line card slot within a short time, install a blank cover panel over the slot and secure it with captive screws by using the screwdriver. Do this to protect the interior of the chassis from dust or other foreign substances and to ensure that the airflow inside the chassis is not disrupted.

Disconnecting a Fiber-Optic Cable from an EX Series Switch

EX Series switches 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 EX Series switch, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines and Warnings for EX Series Switches” on page 269).

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 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.
