11. Model FS518T Fast Ethernet Switch with Gigabit uplinks is an auto sensing 10 100 M bps switch with two 100 1000 Gigabit uplink interfaces This high performance switch is developed primarily to be used either as a segment switch or a desktop switch The Gigabit Ethernet uplink ports on the M odel FS518T switch can be used to connect to the network backbone and shared network resources such as servers at 10 Mbps 100 Mbps or 1000 Mbps The full duplex 1000BASE T ports allow users to connect at high speed to a wiring closet or server located up to 100 meters away on existing Category 5 unshielded twisted pair UTP cable All of the network ports on the M odel FS518T switch can adapt automatically to the speed of the connected network or the PC and the ports can operate at either 10 Mbps or 100 Mbps In addition each port can automatically negotiate with the connected device to operate in full duplex mode If the connected device is operating in half duplex mode only or does not have the capability to participate in the negoti ation process the port will default to half duplex mode The M odel FS518T switch can be used to partition a 10 Mbps or 100 M bps net work to enhance the capacity of the network to support advanced applications In addition the switch provides a link between traditional 10 M bps networks and faster 100 Mbps networks By installing a Model FS518T switch a user can connect any 10 Mbps or 100 M bps device to the switch T
