Chapter 1 Overview The AT-FS705E FC Series and the AT-FS706E FC Series Fast Ethernet switches are unmanaged Layer 2 switches. They can be used in a variety of network configurations and topologies. You can use the switches to create small workgroups with dedicated 10/100 Mbps links to your network devices, such as workstations, servers, printers, and routers. You can also use the switches to interconnect Ethernet hubs to provide a bridge between the different workgroups of your network.

AT-FS705E FC and AT-FS706E FC Installation Guide 10/100 Mbps Twisted Pair Ports The AT-FS705E FC and AT-FS706E FC switches have four twisted pair ports. Type of Connector The twisted pair ports have RJ45 connectors. Speed These ports are compliant with the 10Base-T and 100Base-TX standards and are capable of either 10 Mbps or 100 Mbps operation. The ports are IEEE 802.
Maximum Distance The maximum distance of a twisted pair cable is 100 meters (328 feet). Cable lengths that exceed this limit can result in poor or erratic network performance. Auto MDI/MDI-X An RJ45 twisted pair port on a 10 Mbps or 100 Mbps Ethernet network device can be wired as either MDI and MDI-X. Twisted pair ports on personal computers, routers, and bridges are typically wired as MDI. The twisted pair ports on switches and hubs are usually MDI-X.
AT-FS705E FC and AT-FS706E FC Installation Guide 100 Mbps Fiber Optic Port The AT-FS705E FC and AT-FS706E FC Ethernet switches feature one and two fiber optic ports, respectively. You can use the fiber optic ports to connect the switch to other switches or other end nodes over large distances. Type of Connector The AT-FS705E FC Series and the AT-FS706E FC Series switches come with a variety of fiber optic connectors.
Maximum Distance The maximum operating distance of the fiber optic ports on the AT-FS705E FC and AT-FS706E FC Ethernet switches is 2 kilometers (1.25 miles). Cable lengths that exceed this limit can result in poor or erratic network performance. Note The fiber optic port on the network device that you intend to connect to the AT-FS705E FC or AT-FS706E FC Ethernet switch must have the same operating characteristics as the fiber optic port on the switch.
AT-FS705E FC and AT-FS706E FC Installation Guide Introduction to Ethernet Switching An Ethernet switch is designed to manage the flow of data between the various devices that are connected to its ports. MAC Address Table The heart of an Ethernet switch is the Media Access Control (MAC) address table. Every device that you attach to an Ethernet network has a MAC address. This address is assigned to the device by the device’s manufacturer.
The MAC address table in the AT-FS705E FC Series and AT-FS706E FC Series switches can store up to 4,000 MAC addresses. To prevent the table from becoming filled with addresses of end nodes that are no longer active, the switch has a MAC address aging timer. This timer will delete a MAC address from the table if it does not see a frame from the end node with the address on any port after five minutes (300 seconds).
AT-FS705E FC and AT-FS706E FC Installation Guide How a switch signals an end node to stop transmitting data differs depending on the speed of the end node and switch port. Ports operating at 10 Mbps use flow control while ports operating at 100 Mbps use backpressure. For a 10 Mbps port, the switch will stop an end node from transmitting data by forcing a collision. A collision on an Ethernet network occurs when two nodes attempt to transmit data using the same data link at the same time.
System LEDs The switch has a series of LEDs that you can use to determine the operating status of the system and the ports. The LEDs are described in Table 1. Table 1 System and Port LEDs LED Color Function PWR Steady Green The switch is receiving power. FD Steady Green The fiber optic port is operating in full-duplex mode. OFF The fiber optic port is operating in half-duplex mode. Steady Green The twisted pair port is operating at 100 Mbps. OFF The twisted pair port is operating at 10 Mbps.
AT-FS705E FC and AT-FS706E FC Installation Guide Network Topologies There are a variety of network topologies that you can create with the AT-FS705E FC and AT-FS705E FC Series switches. The first topology shown in Figure 3 is of a power workgroup. Each end node is connected directly to a port on an AT-FS705E FC switch, giving each node a dedicated 10 Mbps or 100 Mbps link. AT-FS705E FC 1 2 4 TX 5 RX DC In 3.
In the topology illustrated in Figure 4, an AT-FS705E FC is used to connect together four 10/100 Mbps Ethernet hubs. Here the switch functions as a bridge between the different workgroups by controlling the flow of data between the workgroups. The switch transfers an Ethernet frame from hub to hub only when the destination node for the frame is on a different hub than the node that originated the frame. This reduces the amount of unnecessary data traffic in each workgroup.
AT-FS705E FC and AT-FS706E FC Installation Guide If your network consists of several AT-FS705E FC and AT-FS706E FC switches, then you will probably want to connect them together to form an integrated network. Here the fiber optic ports can be extremely useful. You can use the ports to create a fiber optic backbone. With a maximum operating distance of 2 kilometers (1.25 miles), the ports can be used to connect together switches that are physically far apart.
If you have more than three AT-FS705E FC or AT-FS706E FC switches that you want to connect together, then you might use an 100Base Ethernet switch that has multiple fiber optic ports to act as a backbone switch. This switch will function as the connection focal point for all the AT-FS705E FC and ATFS706E FC switches in your network. This is often referred to as a collapsed backbone. An example of this topology is illustrated in Figure 6.
AT-FS705E FC and AT-FS706E FC Installation Guide In designing a network topology, be sure your topology does not contain any loops. A loop exists when there is more than one path between any two end nodes in your network. A loop can result in what is referred to as broadcast storms, where Ethernet frames become caught in repeating cycles that needlessly consume network bandwidth. This often results in poor network performance. An example of an invalid loop topology is shown in Figure 7.
