LAN Subsystem
The LAN subsystem consists of the following:
•
Intel 82801GBM ICH7-M
•
Realtek 8111D Gigabit Ethernet Controller for 10/100/1000 Mbits/sec Ethernet LAN
connectivity
•
RJ-45 LAN connector with integrated status LEDs
Additional features of the LAN subsystem include:
•
CSMA/CD protocol engine
•
LAN connect interface that supports the ethernet controller
•
PCI bus power management
⎯
Supports ACPI technology
⎯
Supports LAN wake capabilities
LAN drivers are available from Intel’s World Wide Web site at
.
LAN Status LEDs
Two LEDs are built into the RJ-45 LAN connector located on the back panel (see
Figure 2).
These LEDs indicate the operating states of the LAN.
Figure 2.
LAN Status LEDs
Table 3 describes the LED states when the board is powered up and the LAN
subsystem is operating.
