Intel Desktop Board D845EBG2/D845EPT2 Technical Product Specification
1.11 LAN Subsystem (Optional)
1.11.1 Intel
1.11.2 RJ-45 LAN Connector with Integrated LEDs
32
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:
•
•
•
•
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:
•
•
•
•
•
•
Two LEDs are built into the RJ-45 LAN connector. Table 6 describes the LED states when the
Desktop Board is powered up and the LAN subsystem is operating.
