2. If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-

down block is located, and the other end to a modular wall outlet.

3. Label the cables to simplify future troubleshooting.

Fiber Optic SFP Devices

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or 1000BASE-LH) can be used for a

backbone connection between switches, or for connecting to a high-speed server. Each single-mode fiber port

requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber

optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both

ends.

1. Remove and keep the LC port’s rubber cover. When not connected to a fiber cable, the rubber cover

should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a

clean tissue or cotton ball moistened with alcohol. Dirty fiber terminators on fiber cables will impair the

quality of the light transmitted through the cable and lead to degraded performance on the port.

3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other

device (FIG. 6). Since LC connectors are keyed, the cable can be attached in only one orientation.

4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the

connection is valid.

The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at 1 Gbps full duplex. The

maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type.

The NXA-ENET8POE use lasers to transmit signals over fiber optic cable. The lasers

are compliant with the requirements of a Class 1 Laser Product and are inherently

eye-safe in normal operation. However, you should never look directly at a transmit

port when it is powered on.

When selecting a fiber SFP device, considering safety, please make sure that it can

function at a temperature that is not less than the recommended maximum

operational temperature of the product. You must also use an approved Laser Class

1 SFP transceiver.

FIG. 6 Making Connections to SFP Transceivers

If an SFP transceiver is installed in the slot and has a valid link on its port, the

associated RJ-45 port is disabled and cannot be used.
