1.12 LAN Subsystem (Optional)
The network interface controller subsystem consists of the ICH2, with integrated LAN Media
Access Controller (MAC), and a physical layer interface device. Features of the LAN subsystem
include:
• PCI Bus Master Interface
• CSMA/CD Protocol Engine
• Serial CSMA/CD unit interface that supports the following physical layer interface devices:
82562ET onboard LAN
82562ET/MT (10/100 Mbit/sec Ethernet) on the optional CNR
82562EH (1 Mbit/sec HomePNA
†
) on the optional CNR
• PCI Power Management
Supports APM
Supports ACPI technology
Supports Wake up from suspend state (optional Wake on LAN technology)

®
82562ET Platform LAN Connect Device
The Intel 82562ET component provides an interface to the back panel RJ-45 connector with
integrated LEDs. This physical interface may alternately be provided through the CNR connector.
The Intel 82562ET provides the following functions:
• Basic 10/100 Ethernet LAN Connectivity
• Supports RJ-45 connector with status indicator LEDs
• Full driver compatibility
• Advanced Power Management support
• Programmable transit threshold
• Configuration EEPROM that contains the MAC address
1.12.2 RJ-45 LAN Connector LEDs
Two LEDs are built into the RJ-45 LAN connector. Table 8 describes the LED states when the
board is powered up and the LAN subsystem is operating.
