1.10.2 Gigabit LAN Subsystem (Optional)

The Gigabit (10/100/1000 Mbits/sec) LAN subsystem includes the GMCH (with its CSA
interface), the Intel 82547EI PLC, and an RJ-45 LAN connector with integrated status LEDs.
®
1.10.2.1 Intel 82547EI Platform LAN Connect Device
Intel 82547EI provides the following functions:
•
Basic 10/100/1000 Ethernet LAN connectivity
•
Communication Streaming Architecture (CSA) port provides higher throughput and lower
latencies than the Intel 82562EZ device, resulting in up to 30% higher bus throughput (up to
wirespeed)
•
Full device driver compatibility
•
Programmable transit threshold
•
Configuration EEPROM that contains the MAC address
1.10.2.2 RJ-45 LAN Connector with Integrated LEDs
Two LEDs are built into the RJ-45 LAN connector (as shown in Figure 7). Table 7 describes the
LED states when the board is powered up and the Gigabit LAN subsystem is operating.
