Control / Indicator Description
Power On/Off/Sleep
Switch This button turns the HP NetServer power On or Off, and
if available, also transitions the NetServer between Power
On and sleep states. If sleep states are not available, then
this button only turns power On or Off.
The sleep states are NOS dependent and not available if
your NOS does not support power management based on
the ACPI (Advanced Configuration and Power Interface)
standard. Refer to "Applying Power to the HP NetServer"
and "Sleep States (ACPI)" later in this chapter.
On/Off/Sleep LED This green LED indicator provides the power state of the
NetServer:
Steady green when the NetServer is operating normally.
Off when the NetServer is powered off.
Blinking green at 1-Hz rate indicates the NetServer is in a
sleep state and under ACPI control.
Drive Active LED This yellow LED indicator flashes during SCSI disk drive
activity.
Additional Front Panel Controls and Indicators
The input and storage devices provide additional front panel controls and
indicators, which give control and operational status to the respective device.
