Intel Desktop Board D945GSEJT Product Guide

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 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.

Table 3. LAN Status LEDs
