28 Intel Server Board S845WD1-E Product Guide

Resume on Ring

The operation of Resume on Ring can be summarized as follows:

• Resumes operation from the ACPI S1.

• Requires only one call to access the server.

• Detects incoming call similarly for external and internal modems; does not use the Wake on

Ring connector.

• Requires modem interrupt be unmasked for correct operation.

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 the S845WD1-E server 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

• Support for multiple wake-up events (see Table 7. Wake-up Devices and Events, page30)

• Support for a front panel power and sleep mode switch
