Description
Power 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 not available if
your NOS does not support 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.

activity, including the CD-ROM drive(s), IDE hard disk
drives, and SCSI devices connected to the SCSI controller

LED during any embedded LAN activity.
Off
when there is no LAN activity.

indicators, which give control and operational status of the respective device. The
specific controls and indicators depend on the type and model of the input and
storage devices used. The following controls and indicators are the typical ones
