Resume on Ring

Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The operation of Resume on Ring wakes the system from the S1 or S3 sleep states when a signal is sent to the serial port at the rear or the chassis or to an internally installed modem. Resume on ring can be summarized as follows:

Resumes operation from ACPI S1 or S3 states

Requires only one call to access the computer

Detects incoming call similarly for external and internal modems

Requires modem interrupt be unmasked for correct operation

Wake from USB

USB bus activity wakes the computer from an ACPI S1 or S3 state.

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

Wake from PS/2 Devices

PS/2 device activity, such as moving a PS/2 mouse or pressing a key on a PS/2 keyboard, wakes the computer from an ACPI S1 or S3 state.

Hardware Support

The S875WP1-E server board provides several power management hardware features, including:

Power connector

Fan connectors

Instantly Available PC technology

Instantly Available PC technology and LAN Wake require power from the +5 V standby line. The sections discussing these features describe the incremental standby power requirements.

CAUTION

Ensure that the power supply provides adequate +5 V standby current if Instantly Available PC technology features is used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options.
