AMX NXA-ENET24 dimensions Ethernet Cabling, Mounting, Twisted-Pair Devices, Cabling Guidelines

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 2.44 m (8 feet) of each device

•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 switch into a network, make sure that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000 Base-T operation. Check the following criteria against the current installation of your network:

•Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category 3 or better for 10BASE-T and Category 5 or better for 100BASE-TX and 1000 Base-T.

•Protection from radio frequency interference emissions

•Electrical surge suppression

•Separation of electrical wires (switch related or other) and electromag- netic fields from data based network wiring

•Safe connections with no damaged cables, connectors or shields

Mounting

This switch can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Consult the NXA-ENET24 Hardware Installation Guide, Installing The Switch for information on installing the switch into a rack.

Desktop or Shelf Mounting

1.Attach the four adhesive feet to the bottom of the first switch.

2.Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow.

3.If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter.

4.If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order.

Connecting to a Power Source

To connect a switch to a power source:

1.Insert the power cable plug directly into the AC receptacle located at the back of the switch.

2.Plug the other end of the cable into a grounded, 3-pin socket, AC power source.

Note: For international use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country.

3.Check the front-panel LEDs as the device is powered on to be sure the PWR LED is lit. If not, check that the power cable is correctly plugged in.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T connections.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs). Caution: Do not plug a normal phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.

Connecting to MAX, AVM, WAPs, Breakout Boxes, Servers, Hubs and Switches

1.Attach one end of a twisted-pair cable segment to the device’s RJ-45 con- nector.

2.If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is con- nected to the wiring closet. (See “Network Wiring Connections” on page 25.) Otherwise, attach the other end to an available port on the switch.

•Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

Note: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub.

3.As each connection is made, the green Link LED (on the switch) corre- sponding to each port will light to indicate that the connection is valid.
