DES-1024DEOL EOS
Description
24 Auto-sensing 10/100Mbps Ports
The switch comes with 24 10/100Mbps ports, allowing a small workgroup to flexibly integrate to Ethernet and Fast Ethernet. 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 flow control. This function minimizes dropped packets by sending out collision signals when the port's receiving buffer is full.
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.
Plug-and-Play
With 24 plug-and-play ports, the switch is a perfect choice for workgroups to upgrade performance in a client/server environment. The ports can be connected to servers in full-duplex, or hubs in half-duplex.
Direct Connection to Workstations
With low-cost connection per-port, the switch can be set up for direct connection from the PCs. This relieves data bottleneck by giving each workstation a dedicated bandwidth on the network.
