NETGEAR ProSafe 48xGigabit Smart Switch#

ProSafe 48xGigabit Smart Switch is a 1U high, 48-port Gigabit switch maximizes bandwidth and density for great value and capability. With 48 10/100/1000 Mbps ports, each capable of powering 2000 Mbps of data throughput in full-duplex mode, plus four optional fiber ports, it provides a 96 Gbps backbone and connects servers or power users, delivering large amounts of multimedia, image, and video information. Standards-based, it is ideal for combining 10, 100, and 1000 Mbps devices, as it delivers automatic speed and full/half-duplex sensing plus Auto Uplink on every port. Four hot-swappable small form-factor pluggable (SFP) GBIC slots provide optional fiber connectivity for greater distance. An intuitive, Web-browser interface offers simple switch management, making it a snap to monitor switch performance, configure ports, even setup trunks, VLANs, and prioritization.
