Chapter 1 Overview The AT-8000/8POE Fast Ethernet Switch is designed to simplify the task of creating or expanding an Ethernet, Fast Ethernet, or Gigabit Ethernet network with the power of Power over Ethernet (PoE).
Chapter 1: Overview Features The features of the AT-8000/8POE Fast Ethernet Switch include: 16 Port status LEDs Eight Auto-Negotiating 10/100Base-T twisted pair ports with Power over Ethernet (PoE) capability and one 10/100/1000Base-T port with RJ-45 connectors One combo small form-factor pluggable (SFP) port Auto MDI/MDI-X on the twisted pair ports IEEE 802.3 and IEEE 802.3u compliant IEEE 802.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide Front and Back Panels Figure 1 illustrates the front panel of the AT-8000/8POE Fast Ethernet Switch.
Chapter 1: Overview 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-pin RJ-45 connectors. (For the port pinouts, refer to “Connectors and Port Pinouts” on page 55.) The ports on the AT-8000/8POE Fast Ethernet Switch are 10Base-T and 100Base-TX compliant and are capable of 10 megabits per second (Mbps) and 100 Mbps speeds. The ports are IEEE 802.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide 10/100/1000 RJ-45 Uplink Port SFP Port RS-232 Console 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. The SFP port, port 9, can operate in place of its twisted pair port equivalent to provide fiber optic uplink connectivity.
Chapter 1: Overview LEDs The LEDs on the front panel display the system and port status information. Each port has two LEDs as shown in Figure 3. 1 3 5 7 MAIN DET PORT ON ON ACTIVITY PD ON 100 LINK 9 POWER 2 4 6 8 ACT PD ERR MAX CURRENT 10 LINK ACT UPLINK PORT ACTIVITY 1000 LINK ACT 10/100 LINK ACT 9R 822 10/100Base Twisted Pair Port LEDs Uplink Port LEDs Figure 3. Port LEDs Table 2 describes the LEDs for the 10/100Base-T ports. Table 2.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide Table 2. 10/100Base-T PoE Port LEDs (Continued) LED State Description Amber A valid link has been established on the port and the port is operating in 10Base-T mode. Blinking amber The port is transmitting or receiving data at 10 Mbps. Table 4 describes the Power LED. Table 3. Power LED LED State Description Power Green The switch is powered on and is operating normally. Table 4 describes the LEDs for the uplink ports. Table 4.
Chapter 1: Overview 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 cord provided with the switch. A power cord is supplied with the switch. Note For the power requirements, refer to “Power Specifications” on page 53.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide Power over Ethernet The twisted pair ports on the AT-8000/8POE Fast Ethernet Switch feature Power over Ethernet (PoE). PoE is a mechanism for supplying power to network devices over the same twisted pair cables used to carry network traffic. This feature can simplify network installation and maintenance by allowing you to use the switch as a central power source for other network devices.
Chapter 1: Overview Power Budgeting The AT-8000/8POE Fast Ethernet Switch provides a maximum of 15.4 W of power per port on six of the eight ports for a total power consumption of 95 W, while at the same time furnishing standard 10/100 Mbps Ethernet functionality. The AT-8000/8POE smart power management functionality supports any combination of Ethernet ports (1-8) that supply power for IEEE 802.3af Class 0, 1, 2, or 3 powered devices up to a maximum of 95 watts, as described in Table 5.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide should be able to receive its power from the switch while using either a straight or cross-over cable. The PoE feature on the AT-8000/8POE Fast Ethernet Switch should also work with most legacy PD’s as long as the device can be powered on pins 4, 5, 7, and 8.
Chapter 1: Overview Ethernet Switching Basics An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide Duplex Mode Duplex mode refers to how an end node receives and transmits data. If an end node can receive or transmit data, but not both simultaneously, the end node is operating in what is referred to as half-duplex mode. If an end node can both receive and transmit data simultaneously, the end node is said to be operating in full-duplex mode.
Chapter 1: Overview Back Pressure and Flow Control To maintain the orderly movement of data between the end nodes, an Ethernet switch may periodically need to signal an end node to stop sending data. This can occur under several circumstances. For example, if two end nodes are operating at different speeds, the switch, while transferring data between the end nodes, might need to instruct the faster end node to stop transmitting data to allow the slower end node to catch up.
AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide Network Topologies This section illustrates two network topologies that you can create with the AT-8000/8POE Fast Ethernet Switch: a power workgroup and collapsed backbone. Both types of topologies are described below. Power Workgroup Topology The topology shown in Figure 4 is commonly referred to as a power workgroup topology.
Chapter 1: Overview Collapsed Backbone In the topology illustrated in Figure 5, an AT-9424T Gigabit Ethernet Switch forms the backbone that connects to servers and AT-8000/8POE Fast Ethernet switches using Gigabit Ethernet uplinks. This type of topology is often referred to as a collapsed backbone topology.

AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
Chapter 2: Installation Selecting a Site for the Switch Observe the following requirements when choosing a site for your switch: 34 If you plan to install the switch in an equipment rack, ensure that the rack is safely secured and that it will not tip over. Devices in a rack should be installed starting at the bottom, with the heavier devices near the bottom of the rack. If you are installing the switch on a table, ensure that the table is level and secure.

The default user name is “manager” and the default password is “friend.” The login name and password are case-sensitive. The AT-S81 management software displays the home page. The window contains an image of the front of the switch. Ports that have a link to an end node are green. Ports without a link are grey. An example of a home page is shown in Figure 20. Figure 20.
Chapter 2: Installation Warranty Registration Allied Telesis hardware products are covered under limited warranties. Some products have a longer or more appropriate coverage the others. The AT-8000/8POE Fast Ethernet switch has a limited warranty of Lifetime (24 months Fan & PSU). All Allied Telesis warranties are subject to and provided only on the terms and conditions set out in the Allied Telesis Limited Warranties listed on the Allied Telesis website at http://alliedtelesis.com/support/warranty.
Chapter 3 Troubleshooting This chapter contains information on how to troubleshoot the switch in the event that a problem occurs. Note If you need further assistance, please contact Allied Telesyn Technical Support. Refer to “Contacting Allied Telesis” on page 14. Check the Power LED on the front of the switch.
Chapter 3: Troubleshooting If the port PoE LED is solid amber, then the power required by the connected device is more than the maximum power budget for the port. If this is the case, the connected device may not qualify for connection to the switch. If the port PoE LED is blinking amber, then the overall power budget of the switch was exceeded when the powered device was connected.
