Connecting a Fiber-Optic Cable to 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 connecting a fiber-optic cable to 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 121).

To connect a fiber-optic cable to an optical transceiver installed in an EX Series switch:

WARNING: Do not look directly into a fiber-optic transceiver or into the ends offiber-opticcables. Fiber-optictransceiversandfiber-opticcablesconnected to transceivers emit laser light that can damage your eyes.

1.If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.

2.Remove the rubber safety cap from the optical transceiver. Save the cap.

3.Insert the cable connector into the optical transceiver (see Figure 35 on page 82).
