1.11 LAN Subsystem (Optional)
The Network Interface Controller subsystem consists of the ICH4 (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 82562ET (10/100 Mbit/sec Ethernet) on the
CNR bus
• PCI Power Management
Supports ACPI technology
Supports LAN wake capabilities
The Desktop Board D845GERG2 supports a Gigabit Ethernet Controller option, described below.
1.11.1 Intel
®
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 on the back panel
• Full device driver compatibility
• ACPI support
• Programmable transit threshold
• Configuration EEPROM that contains the MAC address
1.11.2 Intel
®
82540EM Gigabit Ethernet Controller
The Intel 82540EM Gigabit Ethernet Controller (available only on the Desktop Board
D845GERG2) provides the following functions:
• Gigabit Ethernet MAC and PHY layer functions in a single component
• Basic 10/100/1000 Ethernet LAN connectivity
• Integrated PHY for 10/100/1000 Mbit/sec full and half duplex operation
• Supports RJ-45 connector with status indicator LEDs on the back panel
• ACPI support
• Configuration EEPROM that contains the MAC address
1.11.3 RJ-45 LAN Connector with Integrated LEDs
Two LEDs are built into the RJ-45 LAN connector. Table 12 describes the LED states when the
Desktop Board is powered up and the 10/100 LAN subsystem is operating.
