The LAN subsystem consists of the following: 
•  Intel 82875P MCH device with an integrated LAN Media Access Controller (MAC) 
•  Intel 82547EI Platform LAN Connect (PLC) device for Gigabit (10/100/1000 Mbits/sec) 

Ethernet LAN connectivity 

•  RJ-45 LAN connector with integrated status LEDs 
Additional features of the LAN subsystem include: 
•  PCI bus master interface 
•  8-bit CSA port interface (Hublink 1.5) interface that support the 82547EI PLC device 
•  PCI power management

Intel 82547EI provides the following functions: 
•  Basic 10/100/1000 Ethernet LAN connectivity 
•  Communication Streaming Architecture (CSA) port provides higher throughput and lower 

latencies 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 

Two LEDs are built into the RJ-45 LAN connector (as shown in Figure 12).  Table 7 describes the 
LED states when the board is powered up and the 10/100/1000 Mbits/sec LAN subsystem is 
operating.
