AMX NXA-ENET8-2POE Installation Manual

Overview
The NXA-ENET8-2POE (FG2178-63) is a Gigabit Ethernet Layer 2 PoE switch with 8 10/
100/1000BASE-T ports, and 2 Small Form Factor Pluggable (SFP) transceiver slots, (see
Figure 1, Ports 9-10).
The NXA-ENET8-2POE also includes an SNMP-based management agent, which provides
in-band access for managing the switch.
The NXA-ENET8-2POE provides a broad range of powerful features for Layer 2 switching,
delivering reliability and consistent performance for your network traffic. They bring order to
poorly performing networks by segregating them into separate broadcast domains with IEEE
802.1Q compliant VLANs, and empower multimedia applications with multicast switching
and CoS services.

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
Mounting
The NXA-ENET8-2POE can be mounted in a standard 19-inch equipment rack or on a
desktop or shelf. Mounting instructions for each type of site follow (see reverse).
Rack Mounting
Before rack mounting the NXA-ENET8-2POE, pay particular attention to the following
factors:
• Temperature: Check that the rack environment temperature (within a rack assembly)
is within the specified operating temperature range (see the Specifications table).
• Mechanical Loading: Do not place any equipment on top of the rack-mounted unit.
• Circuit Overloading: Be sure that the supply circuit to the rack assembly is not over-
loaded.
