Overview 10/100Base-TX Twisted Pair Ports This section applies to the AT-8524M, AT-8524POE, AT-8550GB, and AT-8550SP switches. Type of Connector The 10/100Base-TX twisted pair ports feature 8-pin RJ-45 connectors. Only four of the pins are used when a port is operating at 10 or 100 Mbps Speed The twisted pair ports are 10/100Base-TX compliant and are capable of 10 megabits per second (Mbps) or 100 Mbps speeds. You can set the port speed manually or, because the ports are IEEE 802.
AT-8500 Series Fast Ethernet Switch Installation Guide Maximum Distance Each twisted pair port has a maximum operating distance of 100 meters (328 feet). Type of Cabling For 10 Mbps operation, Category 3 or better 100 ohm shielded or unshielded twisted pair cabling is required. For 100 Mbps operation, Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling is required. Auto-MDI/ MDI-X The twisted pair ports are auto-MDI/MDI-X.
Overview 10/100/1000Base-T Twisted Pair Ports This section applies to Port 49R and Port 50R on the AT-8550GB and AT-8550SP switches. Type of Connector Speed The ports have 8-pin RJ-45 connectors. The ports use four pins when operating at 10 or 100 Mbps and all eight pins when operating at 1000 Mbps. The ports can operate at 10, 100, or 1000 Mbps. The speed is set automatically through Auto-Negotiation or you can set the speed to 10 or 100 Mbps manually through the management software.
AT-8500 Series Fast Ethernet Switch Installation Guide Auto-MDI/ MDI-X The ports are auto-MDI/MDI-X. They automatically configure themselves as either MDI or MDI-X. This feature allows you to use a straight-through twisted pair cable to connect any type of device to a port. Note The auto-MDI/MDI-X feature on a 10/100/1000Base-T port is functional only when the port is set to Auto-Negotiation. If you disable Auto-Negotiation and set the port’s speed and duplex mode manually, the port defaults to MDI-X.
Overview 100Base-FX Fiber Optic Ports This section applies to the AT-8516F/SC switch. Type of Connector Speed Duplex Mode Maximum Distance Type of Cable The fiber optic ports on the AT-8516F/SC switch have dual SC connectors. The fiber optic ports have a fixed operating speed of 100 megabits per second (Mbps). The speed cannot be changed. The fiber optic ports can operate in either half- or full-duplex mode.
AT-8500 Series Fast Ethernet Switch Installation Guide Power Over Ethernet The following discussion applies only to the AT-8524POE switch. The twisted pair ports on the AT-8524POE switch offer the same features and functionality as the twisted pair ports on the other switches in the series. As such, they can operate at 10 or 100 Mbps, feature AutoNegotiation and Auto-MDI/MDI-X, and so forth. But they do have an importance difference in that they also feature Power over Ethernet (PoE).
Overview A port on the switch connected to a powered device can supply up to 15.4 watts of power to the device, while at the same time furnishing standard 10/100 Mbps Ethernet functionality. A port connected to a network node that is not a powered device (that is, a device that receives its power from another power source) functions as a regular Ethernet port, without PoE. The PoE feature remains enabled on the port but no power is delivered to the device.
AT-8500 Series Fast Ethernet Switch Installation Guide You can, using the AT-S62 management software, enable or disable PoE on a per-port basis. You can also reduce the maximum amount of power a port can receive, from the maximum of 15.4 W. However, configuring PoE on an AT-8524POE switch will probably be unnecessary. As already mentioned, the power supply in the switch can provide enough power to meet the needs of all 24 base ports, even if all are connected to power devices requiring the maximum of 15.
Overview GBIC and SFP Expansion Slots The AT-8550GB and AT-8550SP switches have two GBIC expansion slots and two SFP expansion slots, respectively. The slots are labelled Port 49 and Port 50. Each slot can accommodate one optional fiber optic Gigabit Interface Converter (GBIC) Ethernet module or Small Form-factor Pluggable (SPF) module, also referred to as a mini-GBIC. These modules are a fast and easy way for you to add an 1000 Mbps fiber optic port to your Fast Ethernet switch.
AT-8500 Series Fast Ethernet Switch Installation Guide Module Expansion Slots The AT-8516F/SC, AT-8524M, and AT-8524POE switches have two expansion slots.

The unit can provide power to the switch in the event the switch’s internal power supply should fail. The AT-RPS3004 redundant external power supply comes with one preinstalled AT-PWR3004 Power Module and has three empty slots for additional power modules.
AT-8500 Series Fast Ethernet Switch Installation Guide AC Power Connector The switch has a single AC power supply socket on the back panel, which has autoswitch AC inputs. To power the switch on or off, you connect or disconnect the power cord. Refer to Technical Specifications on page 77 for the input voltage range.
Overview DC Power Connector Some models of the AT-8500 Series switch are offered with a DC terminal block on the back panel instead of an AC socket, for those network installations that require DC equipment. Refer to Technical Specifications on page 77, for the input voltage range and Wiring a DC Powered Unit on page 66, for instructions on how to wire a DC powered unit.
AT-8500 Series Fast Ethernet Switch Installation Guide A Few Basics about Ethernet Switching 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 in your network has a MAC address and each MAC address is unique. The address is assigned to a device by the device’s manufacturer.
Overview Duplex Mode Duplex mode refers to the manner in which 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 halfduplex mode. If an end node can both receive and transmit data simultaneously, the end node is said to be operating in full-duplex mode.
AT-8500 Series Fast Ethernet Switch Installation Guide Store and Forward Backpressure and Flow Control These Fast Ethernet switches use store and forward as the method for receiving and transmitting frames. When an Ethernet frame is received on a switch port, the switch does not retransmit the frame out the destination port until it has received the entire frame and stored the frame in a port buffer. It then examines the frame to determine if it is a valid frame.
Overview Network Topologies This section illustrates several of the network topologies you can create with the AT-8500 Series Fast Ethernet switch. Power Workgroup Topology The topology shown in Figure 8 is commonly referred to as a power workgroup topology. Each workstation or end node is connected directly to a port on an AT-8524M Fast Ethernet Switch. This provides each end node with a dedicated data link to the switch for best performance and reliability.
AT-8500 Series Fast Ethernet Switch Installation Guide Collapsed Backbone Topology In the topology illustrated in Figure 9, an AT-8524M Fast Ethernet Switch connects together 10/100 Mbps Ethernet hubs. This type of topology is often referred to as a collapsed backbone topology. The switch functions as the focal point of the network by acting as a bridge between the different workgroups.
Overview Mixed Topology You can always combine topologies as well as build a larger network by connecting different switches together. If the switches are within 100 meters (328 feet) of each other, you can use the twisted pair ports. If the switches are further apart, then you can use fiber optic ports. Figure 10 illustrates a network of three AT-8524M Fast Ethernet switches. The workstations and servers on the network are connected either directly to a switch or indirectly through an Ethernet hub.
Chapter 2 Installation This chapter contains the installation procedures for the switch.
