About Network Interface Options

The system's main logic board provides an auto-sensing, switchable 10BASE-T/
100BASE-TX Ethernet interface conforming to the IEEE 802.3u Ethernet standard. The
interface configures itself automatically for either 10-Mbps or 100-Mbps operation,
depending on network characteristics.
Two rear panel connectors provide access to the Ethernet interface:
4 One RJ-45 connector for connecting a twisted-pair Ethernet (TPE) cable
