The latest hardware revision of the switch (D1) introduces the first energy-saving features in the networking arena. By sensing whether attached devices are ON or OFF and estimating the cable length, the switch is able to adjust its power consumption, for a total saving of up to 27%. This desktop switch offers an economical way for the SOHO and small and medium business (SMB) to benefit from the increased bandwidth of Gigabit Ethernet. It provides 5 Gigabit ports for fast server deployment to meet increasing network load. With plugand- play installation and copper Gigabit ports capable of connecting to your existing Cat. 5 twisted-pair cable, this device instantly enhances your workgroup's performance without requiring you to install expensive fibre cables or to go through complex reconfiguration. 5 Gigabit ports provide an inexpensive alternative solution to fibre-optic. Using your existing low-cost Cat. 5 copper twisted-pair wires as the transmission media, these ports allow you to instantly upgrade your servers to Gigabit capability without requiring you to install new, expensive fibre cables. All ports support 10/100/1000Mbps network speed auto-sensing and full/half duplex auto-negotiation. The Gigabit ports provide dedicated bandwidths for your servers running at 2000Mbps full-duplex. This gives workstations bottleneck-free paths to simultaneously access server data.
