8 Auto-sensing 10/100Mbps Ports

The switch comes with 8 10/100Mbps ports, allowing a small workgroup to flexibly connect to Ethernet ad Fast Ethernet and integrate. These intelligent ports detect the network speed and auto-negotiate between 100BASE-TX and 10BASE-T, as well as between full- and half-duplex.

Flow Control for Secure Transmission

All ports support 802.3x flow control. This function minimizes dropped packets by sending out collision signals when the port's receiving buffer is full. Flow control is available in the full-duplex mode.

Auto-negotiation of MDI/MDIX Cross Over

All ports support auto-negotiation of MDI/MDIX cross over. This eliminates the need for cross over cables or uplink ports. Any port can simply plug to a server, a hub or a switch, using the usual straight-through twisted-pair cable.

SOHO Plug-and-Play

With 8 plug-and-play ports, the switch is a perfect choice for the small workgroup to upgrade performance in a client/server environment. The ports can be connected to servers in full-duplex, or hubs in half-duplex.

Desktop Power

With low-cost connection per-port, the switch can also be set up for direct connection from the PCs. This relieves data bottleneck by giving each workstation a dedicated bandwidth on the network.
