Power Management Features

Power management is implemented at several levels, including:

Software support through Advanced Configuration and Power Interface (ACPI)

Hardware support:

Power connector

Fan connectors

LAN wake capabilities

Instantly Available PC technology

Resume on Ring

Wake from USB

Wake from PS/2 devices

Power Management Event (PME#) wake-up support

Wake on LAN Technology

Network adapters that are PCI 2.2 compliant assert the wake-up signal using the PCI bus signal PME# (pin A19 on the PCI bus connectors).

CAUTION

For Wake on LAN technology, the 5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing Wake on LAN technology can damage the power supply.

CAUTION

If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the server board may lose register settings stored in memory, etc.

Wake on Ring

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

Powers up the server from the ACPI S5 state.

Modem must support PME.

Requires two calls to access the server:

The first call powers up the server

The second call enables access (when the appropriate software is loaded)

For external modems, hardware on the server board monitors the ring indicate (RI) input of the serial port.
