Control / Indicator Description
On/Off/Sleep LED
This green LED indicator provides the power state of the Server:
Steady green when the Server is operating normally.
Off when the Server is powered off.
Steady amber indicates the Server is in a sleep state and under ACPI
(Advanced Configuration and Power Management Interface) control.
Power On/Off/Sleep Switch
This button turns the HP Server power On or Off, and if available, also
transitions the Server 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 only available if your NOS supports
power management based on the ACPI (Advanced Configuration and Power
Management Interface) standard. Refer to "Applying Power to the HP Server"
and "Sleep States (ACPI)" later in this chapter.
Drive Active LED
Flickering orange LED during any IDE or SCSI device activity, including the
CD-ROM drive(s), IDE hard disk drives, and SCSI devices connected to the
SCSI controller board.
Off when there is no IDE or SCSI device activity.
