Network Wiring Connections; Fiber Optic Sfp Devices - AMX NXA-ENET8-2POE Instruction Manual

3. As each connection is made, the Link LED (on the NXA-ENET8-2POE) corresponding to each port will turn on (green or amber)
to indicate that the connection is valid.

Network Wiring Connections

Typically, a punch-down block is an integral part of newer equipment racks, as part of the patch panel (FIG. 21).

Instructions for making connections in the wiring closet with this type of equipment follow:
1. Attach one end of a patch cable to an available port on the NXA-ENET8-2POE, and the other end to the patch panel.
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. See the Cable Labeling and Connection Records section on page 30.

Fiber Optic SFP Devices

An optional Gigabit SFP (1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or 100BASE-FX) transceiver 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.
NOTE: These switches use lasers to transmit signals over f iber 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.
NOTE: When selecting a f iber 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.
1. Remove and keep the Fiber port's rubber plug.
When not connected to a fiber cable, the rubber plug 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 a little ethanol.
Dirty fiber terminators on fiber optic 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 SFP port on the switch and the other end to the SFP port on the other device.
Since SFP connectors are keyed, the cable can be attached in only one orientation (FIG. 22).
