ACPI technology support . LAN wake capabilities • LAN subsystem software For information about Refer to LAN software and drivers 1.10.1 Intel® 82579L Gigabit Ethernet Controller The Intel 82579L Gigabit Ethernet Controller supports the following features: • 10/100/1000 BASE-T IEEE 802.3 compliant • Energy Efficient Ethernet (EEE) IEEE802.3az support [Low Power Idle (LPI) mode] • Dual interconnect between the Integrated LAN Controller and the Physical Layer (PHY): . PCI Express-based interface for active state operation (S0) state . SMBUS for host and management traffic (Sx low power state) • Compliant to IEEE 802.3x flow control support • 802.1p and 802.1q • TCP, IP, and UDP checksum offload (for IPv4 and IPv6) • Full device driver compatibility • Provides lower power usage to meet Energy Star 5.0 and ErP specifications 1.10.2 LAN Subsystem Software LAN software and drivers are available from Intel’s World Wide Web site. For information about Refer to Obtaining LAN software and drivers 1.10.3 RJ-45 LAN Connector with Integrated LEDs Two LEDs are built into the RJ-45 LAN connector (shown in Figure 5). Item Description A Link LED (Green) B Data Rate LED (Green/Yellow) Figure 5. LAN Connector LED Locations Table 5 describes the LED states when the board is powered up and the LAN subsystem is operating. Table 5. LAN Connector LED States LED LED Color LED State Condition Link Green Off LAN link is not established. On LAN link is established. Blinking LAN activity is occurring. Data Rate Green/Yellow Off 10 Mbits/s data rate is selected. Green 100 Mbits/s data rate is selected. Yellow 1000 Mbits/s data rate is selected. 1.11 Hardware Management Subsystem The hardware management features enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features, including the following: • Fan monitoring and control • Thermal and voltage monitoring • Chassis intrusion detection 1.11.1 Hardware Monitoring and Fan Control The hardware monitoring and fan control subsystem is based on the Winbond W83677HG-I device, which supports the following: • Processor and system ambient temperature monitoring • Chassis fan speed monitoring • Power monitoring of +12 V, +5 V, +3.3 V, V_SM1, V_SM2, 3.3V_Standby and +VCCP • SMBus interface 1.11.2 Fan Monitoring Fan monitoring can be implemented using Intel® Extreme Tuning Utility, Intel® Desktop Utility, or third-party software. For information about Refer to The functions of the fan headers Section 1.12.2.2, page 34 1.11.3 Chassis Intrusion and Detection The board supports a chassis security feature that detects if the chassis cover is removed. The security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion header. When the chassis cover is removed, the mechanical switch is in the closed position. For information about Refer to The location of the chassis intrusion header Figure 12, page 46 1.11.4 Thermal Monitoring Figure 6 shows the locations of the thermal sensors and fan headers. Item Description A Rear chassis fan header B Processor fan header C Thermal diode, located on processor die D Front chassis fan header E Intel X79 Express Chipset F Auxiliary fan header Figure 6. Thermal Sensors and Fan Headers 1.12 Power Management Power management is implemented at several levels, including: • Software support through Advanced Configuration and Power Interface (ACPI) • Hardware support: . Power connector . Fan headers . LAN wake capabilities . Instantly Available PC technology . Wake from USB . PME# signal wake-up support . WAKE# signal wake-up support . Wake from Consumer IR . Wake from S5 . Power Supervisor . +5 V Standby Power Indicator LED 1.12.1 ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with this board requires an operating system that provides full ACPI support. ACPI features include: • Plug and Play (including bus and device enumeration) • Power management control of individual devices, add-in boards (some add-in boards may require an ACPI-aware driver), video displays, and hard disk drives • Methods for achieving less than 15-watt system operation in the power-on/standby sleeping state • A Soft-off feature that enables the operating system to power-off the computer (refer to the Advanced Configuration and Power Interface Specification at • Support for multiple wake-up events (see Table 8 on page 32) • Support for a front panel power and sleep mode switch Table 6 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system.
