      Show Part Numbers

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 82562ET (10/100 megabits per second Ethernet) on the CNR bus
  • PCI Power Management
    • Supports ACPI technology
    • Supports LAN wake capabilities

Intel® 82562ET Platform LAN Connect Device

The Intel 82562ET component provides an interface to the back panel RJ-45 connector with integrated light emitting diodes (LEDs). This physical interface may alternately be provided through the CNR connector.

The Intel 82562ET provides the following functions:

  • Basic 10/100 Ethernet 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
