Product Description

1.11 LAN Subsystem

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 support the 82547EI

• PCI power management

 Supports ACPI technology

 Supports LAN wake capabilities

1.11.1 10/100 Mbits/sec LAN Subsystem

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
