Product Overview
Auto-sensing 10/100 ports
The DES-1008A uses auto-sensing 10/100 Mbps ports, allowing a small workgroup to flexibly connect to Ethernet and Fast Ethernet devices to create an integrated network. These ports detect the network speed and auto-negotiate between 10BASE-T and 100BASE-TX, as well as between full and half-duplex, allowing you to get the maximum speed possible for each device connected to your network.
Auto MDI/MDIX CrossOver
All ports support automatic MDI/MDIX crossover, eliminating the need for crossover cables or uplink ports. Each port can be plugged directly to a server, hub, router, or switch using regular straight-through twisted-pair Ethernet cables.
Flow Control for Secure Transmission
802.3x flow control on each port minimizes dropped packets when the port’s receiving buffer is full. This gives you a more reliable connection for all of your connected devices.
