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. Fi

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 802.3u Auto-negotiation-compliant, meaning the speed for each port is set automatically by the switch after determining the speed

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. When connecting two network devices

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. Contact your Allied Telesyn International sales representative for a list

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. For example, the maximum operating di

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. For example, each network interface card (NIC) that y

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). The aging timer also helps to ensure that the table is correct should an end

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. A
