 +The Ethernet port of a DHD device complies to the standard 100Base-TX IEEE 802.3u (52/XC, 52/XD, 52/XS) and 1000BASE-T (52/XC2, 52/XD2, 52/​XS2). ​

 +**Warning**\\ ​ Never try to connect a DHD device to a network running on 10 Mbit/s! \\ Even if it looks like this might work, in fact it will not!

 +/* The Ethernet interface of a DHD device operates with the following speed:
 +
 +>100 Mbps - Half Duplex */
 +
 +If you connect other network equipment to a DHD device, please ensure it is able to handle these specifications. However, if you experience connection problems, make sure the requirements are met. This is particularly important if you connect a PC directly to a DHD device using a crossover Ethernet cable. If you do this, make sure you have set the properties of the network adapter to the right values. Use "​Auto-Detect"​ option, that are provided by the most network adapters.

 +<WRAP center round important 80%>
 +**Important**\\ ​ You can operate several DHD devices as well as one or several server PCs within the same network segment.
 +
 +However, you should always use **Switches** for networking. **Never** use hubs! Switches provide much better data throughput, because they eliminate collisions between network packets.
 +</​WRAP>​
 +
 +We recommend using switches that automatically adjust their port speed to the speed of the node connected to a particular port. Also, make sure all devices on a shared network can exchange data on the ports and protocols described in the next section.
