The speed migration design will bridge a bandwidth-intensive Fast Ethernet network and a traditional 10Mbps Ethernet network. The 10/100 Fast Ethernet Switch complies with IEEE802. 3u, 100BASE-TX, IEEE802. 3 and 10BASE-T standards. The switch has two ports, one of which is a 10/100Mbps, N-Way, RJ-45 port. The twisted-pair connector (UTP/STP) of Port 1 is a 10/100Mbps, N-Way RJ-45 port for use with unshielded or shielded twisted-pair cabling. Because it is an N-Way port, the operating mode of connected stations (10Mbps Ethernet or 100Mbps Fast Ethernet) is automatically detected and the port is auto-configured to match. Please use crossover cabling unless you are connecting to a straight-through uplink port on a switch or hub. The twisted-pair connector operates at an user-selectable effective speed of 10 or 100Mbps for half-duplex mode and 20 or 200Mbps for full-duplex mode. In either mode, the twisted-pair connector can operate up to 100 meters of Category 3, 4, or 5 UTP/STP cable. The BNC connector is a standard connector for use with thin Ethernet coaxial cabling (half-duplex mode only). The AUI connector is for attaching the switch to an external transceiver for a thick Ethernet or Fiber-optic connection (half-duplex mode only). Important Note: The Port 1 connectors are arranged in a "priority" scheme. That is, one connector has a higher priority than the other two, so if a device is connected to that connector, the other connectors are disabled. The priority is: UTP/STP ­ highest priority; AUI ­ second priority; BNC ­ lowest priority. [. . . ] The attached device must be within 100 meters of the 10/100 Fast Ethernet Switch. A crossover-type cable must be used for the connection unless connecting to an uplink capable switch or hub. Setting the Duplex Mode Both twisted-pair ports of the device can be set for half-duplex or full-duplex operation (the BNC and AUI ports are half-duplex only). At half-duplex operation, packet transmission and reception do not occur simultaneously, thus communication speed is limited to 10 or 100Mbps using either port. During full-duplex operation, packet transmission and reception occur simultaneously, thus communication speed is doubled to 20 or 200Mbps using either port. [. . . ]
