This card is designed for bandwidth-demanding mission-critical client/server applications. It provides 4 Fast Ethernet ports for a very fast trunk link to a Fast Ethernet switch. The card plugs into the server\'s PCI expansion slot. Connection to the switch is over the twisted-pair copper cable. Each of the 4 ports can establish an independent full-bandwidth segment with a Fast Ethernet switch. When all 4 ports are connected to a switch an 800Mbps trunk (aggregate-bandwidth with 4 Fast Ethernet ports running at full duplex) is created for high-speed simultaneous access by workstations.
