Product Description LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. The sections discussing these features describe the incremental standby power requirements for each. Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The method used depends on the type of telephony device (external or internal). ✏ NOTE The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an operating system that provides full ACPI support. 1.13.2.1 Power Connector ATX12V- and SFX12V-compliant power supplies can turn off the system power through software control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer's response can be set using the Last Power State feature in the BIOS Setup program's Boot menu. For information about The ATX specification Refer to Section 1.4, page 13 1.13.2.2 Fan Connectors Table 13 summarizes the function/operation of the fan connectors for boards with a hardware monitoring ASIC18.
