NXA-ENET8POE Gigabit PoE Ethernet Switch 10/100/1000BASE-T Ports The switch contains eight RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports on the switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.
Network Planning Network Planning Introduction To Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
Network Planning Power-over-Ethernet Devices 10/100 Mbps Full Duplex Servers 1000 Mbps Full Duplex Network Segment 100 Mbps Full Duplex Standard LAN PoE Workstations 100 Mbps Full Duplex FIG. 3 Collapsed Backbone Meeting Room With eight 1000 Mbps parallel bridging ports (i.e., eight distinct collision domains), the NXA-ENET8POE can function as an efficient bridged node that is ideal for a meeting room environment. Zero noise makes the switch unobtrusive for such a setting. In FIG.

Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch).
Network Planning Installing the NXA-ENET8POE Selecting a Site The NXA-ENET8POE can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. The site should: Be at the center of all the devices you want to link and near a power outlet.
Network Planning Connecting to a Power Source To connect a device to a power source: 1. Insert the power cable plug directly into the socket located at the back of the device (FIG. 1). 2. Plug the other end of the cable into a grounded, three-pin, AC power source. 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 socket type in your country. 3. Check the front-panel LEDs as the device is powered on to be sure the Power LED is on.
Network Planning Making Network Connections Connecting Network Devices The NXA-ENET8POE is designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to devices using optional SFP transceivers. If 802.3af-compliant PoE devices are connected to the switch’s 10/100 Mbps ports, the NXA-ENET8POE automatically supplies the required power.
Network Planning 2. If not already in place, attach one end of a cable segment to the back of the patch panel where the punchdown 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.
Network Planning Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
Network Planning Cable Labeling and Connection Records When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption. To best manage the physical implementations of your network, follow these guidelines: Clearly label the opposing ends of each cable.

Appendix B: Cables Appendix B: Cables Twisted-Pair Cable and Pin Assignments For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
Appendix B: Cables Straight-Through Wiring If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on the NXA-ENET8POE, you can use either straight-through or crossover cable to connect to any device type.) You must connect all four wire pairs as shown in Straight-Through Wiring section on page 56 to support Gigabit Ethernet connections.
Appendix B: Cables 1000BASE-T Pin Assignments All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.
