Desktop Board Features

LAN Subsystem

The LAN, based on the RealTek RTL8102EL Ethernet Controller, provides the following functions:

10/100 Mb/s Ethernet LAN

Support for RJ-45 connector with status indicator LEDs

Programmable transit threshold

Configurable EEPROM that contains the MAC address

LAN Subsystem Software

For LAN software and drivers, refer to the D945GCLF link on Intel’s World Wide Web site at http://support.intel.com/support/motherboards/desktop.

LAN Status LEDs

Two LEDs are built into the RJ-45 LAN connector located on the back panel (see Figure 3). These LEDs indicate the operating states of the LAN.

Figure 3. LAN Status LEDs

Table 3 describes the LED states when the board is powered up and the LAN subsystem is operating.
