This switch provides 24 10/100 Mbps ports to connect to 24 workstations & servers. All ports auto-sense the network speed of the computers & hubs to run at either 10 Mbps or 100 Mbps. All ports auto-negotiate between full & half duplex, flow control, & MDI/MDIX twisted-pair cross over. This switch provides an open slot for you to install 2 optional Fast Ethernet fiber ports to attach to 2 servers or cascading switches over the 2 km long reliable fiber cables. Expansion is easy through any twisted-pair port. You cascade several switches together through this port to get more ports. IEEE 802.3x Flow Control allows your servers to directly connect to this switch for fast, reliable data transfer. At 200 Mbps full duplex, this switch provides high-speed data pipes to your servers with minimum data transfer loss. Auto-negotiation of MDI/MDIX cross over eliminates the need for cross over cables or uplink ports. Any port can simply plug to a server, workstation, or hub using the usual straight through twisted-pair cable. Please note: networking components such as switches, routers & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
