Auto-Sensing 10/100 Ports
The DES-1008E 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.
Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic and network overhead, lower actual data throughtput rate.
