LAN Subsystem The Network Interface Controller subsystem consists of the ICH5 (with integrated LAN Media Access Controller) and a physical layer interface device. Feature 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: o Intel® 82562EZ 10/100 Mbit/sec Platform LAN Connect (PLC) device • PCI Power Management o Supports APM o Supports ACPI technology o Supports Wake up from suspend state (Wake-On-LAN † technology) Intel ® 82562EZ Platform LAN Connect Device The Intel 82562EZ 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 82562EZ 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 RJ-45 LAN Connector LEDs Two LEDs are built into the RJ-45 LAN connector. The following table describes the LED states when the board is powered up and the LAN subsystem is operating. Table 7: LAN Connector LEDs LED Colour LED State Green Off Green On Yellow Off Yellow On (steady state) Yellow On (brighter and pulsing) Condition 10 Mbit/sec data rate is selected. 100 Mbit/sec date rate is selected. LAN link is not established. LAN link is established. The computer is communicating with another computer on the LAN. D865GLC Motherboard Manual 26
