Installation
Selecting a Site
The site should:
Be at the center of all the devices you want to link and near a power outlet.
Be able to maintain its temperature within 0° to 50°C (32° to 122°F) and its humidity within 10% to 90%, non-condensing
Provide adequate space (approximately two inches) on all sides for proper air flow
Be accessible for installing, cabling and maintaining the devices
Allow the status LEDs to be clearly visible
Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting fixtures and other sources of electrical
interference, such as radios and transmitters.
Make sure that the unit is connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz, is within 2 m
(6.6 feet) of each device and is powered from an independent circuit breaker. As with any equipment, using a filter or surge
suppressor is recommended.
Ethernet Cabling
To ensure proper operation when installing the NXA-ENET8-2POE into a network, make sure that the current cables are suitable for
10BASE-T, 100BASE-TX, or 1000BASE-T operation.
Check the following criteria against the current installation of your network:
Cable type: Un-shielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category 3 or
better for 10BASE-T, Category 5 or better for 100BASE-TX, and Category 5, 5e, or 6 for 1000BASE-T.
Protection from radio frequency interference emissions
Electrical surge suppression
Separation of electrical wires (switch related or other) and electromagnetic fields from data based network wiring
Safe connections with no damaged cables, connectors or shields
