S4 state is dependent on an OS that supports this wake event. 2. For LAN and PME#, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state. ✏ NOTE The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events. Hardware Support The S845WD1H server board provides several power management hardware features, including: • Power connector • Fan connectors • LAN wake capabilities • Instantly Available PC technology • Resume on Ring • Wake from USB • Wake from PS/2 keyboard • PME# wake-up support 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). Description 29
