15 Chapter 1 Overview The AT-8000/8POE Fast Ethernet Switch is designed to simp lify the task of creating or expanding an Ethernet, Fa st Ethernet, or Gigabit Eth ernet network with the powe r of Power over Ethernet (PoE).
Chapter 1: Ove rview 16 Features The features of the AT-8000/8POE Fast Ethernet Switch include: Port status LEDs Eight Auto-Negotiating 10/100Base-T twiste d pair port s with Power over Ethern.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Gui de 17 Front and Back Panels Figure 1 illustrates the front panel of the AT-8000/8POE Fast Ethernet Switch. Figure 1. AT-8000/8POE Front Panel Figure 2 illustrates the back panel o f the AT-8000/8POE Fast Ethernet Switch.
Chapter 1: Ove rview 18 Ports The AT-8000/8POE Fast Ethernet Switch features eight twisted pair ports, one 10/100/1000Base-T port, and one combo SFP port. Twisted Pair Ports The twisted pair ports feature 8-pi n RJ-45 connectors. (For the port pinouts, refer to “Connectors a nd Port Pinouts” on page 55.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Gui de 19 10/100/1000 RJ-45 Uplink Port The 10/100/1000Base-T uplink port is a backup for the SFP uplink port. If the SFP’s fiber connection fails, the 10/100/1000Base-T uplink port takes over the connection.
Chapter 1: Ove rview 20 LEDs The LEDs on the front panel display the system and po rt status information. Each port has two LEDs as shown in Figure 3. Figure 3.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Gui de 21 Table 4 describes the Powe r LED. Table 4 describes the LEDs for the uplink ports. Amber A valid link has been establishe d on the port and the port is operating in 10 Base-T mode. Blinking amber The port is transmitting or receiving data at 10 Mbps.
Chapter 1: Ove rview 22 Power Supply The switch has an internal power supply with a single AC power supply socket on the back panel which features autoswitch AC inputs. To power the switch on or off, connect or disconnect the power co rd provided with the switch.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Gui de 23 Power over Ethernet The twisted pair ports on the AT-8000/8POE Fast Ethernet Switch f eature Power over Ethernet (PoE). PoE is a mechanism for supplying power to network devices over t he same twisted pair cables used to carr y network traffic.
Chapter 1: Ove rview 24 Power Budgeting The AT-8000/8POE Fast Ethernet Switch p rovides a maximum of 15.4 W of power per port on six of the eight ports fo r a total power consumption of 95 W, while at the same time furnishing standard 10/100 Mb ps Ethernet functionality.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Gui de 25 should be able to receive its power fr om the switch while using either a straight or cross-over cable.
