The LAN subsystem consists of the following: 

• 

Physical layer interface device.  As a manufacturing option, the board includes one of the 
following Platform LAN Connect (PLC) devices: 

 

Intel 82562EZ PLC for 10/100 Mbits/sec Ethernet LAN connectivity 

 

Intel 82547EI PLC 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 

• 

CSMA/CD protocol engine 

• 

Serial CSMA/CD unit interface that supports the 82562EZ 

• 

8-bit CSA port interface that supports the 82547EI 

• 

PCI power management 

 

Supports ACPI technology 

 

Supports LAN wake capabilities 

The 10/100 Mbits/sec LAN subsystem includes the ICH5 (with its CSMA/CD interface), the Intel 
82562EZ PLC, and an RJ-45 LAN connector with integrated status LEDs 

®

The Intel 82562EZ provides the following functions: 

• 

Basic 10/100 Ethernet LAN connectivity 

• 

Full device driver compatibility 

• 

Programmable transit threshold 

• 

Configuration EEPROM that contains the MAC address 

Two LEDs are built into the RJ-45 LAN connector (shown in Figure 13 below).
