This system includes a network interface controller (NIC) integrated on the system board. The
NIC is based on the Texas Instruments TLAN3.1 component and provides direct, auto-sensing
support for 10BaseT and 100BaseTX LANs. Using an optional adapter, connection to a 10Base2
system is possible. Network status indicators are provided on the rear of the chassis.
The NIC supports the Magic Packet method of waking up the system from a powered-down state.
