1.9 LAN Subsystem
The Network Interface Controller subsystem consists of the ICH2 (with integrated LAN Media
Access Controller) 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:
 82562EM onboard LAN
 82562ET/EM (10/100 Mbit/sec Ethernet) on CNR bus
 82562EH (1 Mbit/sec HomePNA
†
) on CNR bus
• PCI Power Management
 Supports APM
 Supports ACPI technology
 Supports Wake up from suspend state (Wake on LAN
†
technology)

82562EM Platform LAN Connect Device (Optional)
The Intel 82562EM component provides an interface to the back panel RJ-45 connector with
integrated LEDs. This physical interface may alternately be provided via the CNR connector.
The Intel 82562EM provides the following functions:
• Basic 10/100 Ethernet LAN connectivity
• Supports RJ-45 connector with status indicator LEDs on the back panel
• Full device driver compatibility
• Advanced Power Management and ACPI support
• Programmable transit threshold
• Configuration EEPROM that contains the MAC address
• Remote monitoring (alerting)
1.9.2 RJ-45 LAN Connector with Integrated LEDs (Optional)
Two LEDs are built into the RJ-45 LAN connector. Table 6 describes the LED states when the
board is powered up and the LAN subsystem is operating.
