HP D5970A - NetServer - LCII User Manual page 14

Chapter 1
The Netserver supports certain types of system activity, which is used as wake-up
events from these sleep states. These wake-up events can be generated from the
power button, LAN activity, and scheduled events.
NOTE The HP Netserver's power management policies (transitions
between various power states) and the user options are specific
to the particular ACPI-compliant NOS installed on the
Netserver. If your NOS is ACPI-compliant, refer to the power
management features in the instructions provided for more
information.
The HP Netserver's power button can be configured to initiate a graceful
shutdown of the NOS rather than an immediate shutdown of the power supply.
The power button configurations are dependent on the user interface provided by
the ACPI-compliant NOS. While power management is under the control of the
ACPI-compliant NOS, the HP Netserver's power button is capable of an override
in case of a non-responsive NOS.
NOTE The HP Netserver power button will force a power-down
without waiting for the NOS to gracefully shut down the
Netserver, if the power button is pressed and held more than
four seconds.
CAUTION If the power button override is used, there is a strong
possibility that data will be corrupted or lost.
