Control / Indicator 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.
Blinking green when the Server is in standby mode.
Off when the Server is powered off.
Red (steady or flashing) indicates a preboot error or a
POST error that is preventing the system from booting.
Power On/Off/
Sleep Switch
The power switch turns the HP server power On or Off. If
sleep states are available, it also transitions the Server
between Power On and sleep states.
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 Activity LED Flickering amber 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.
Additional Controls and Indicators
Storage devices provide additional front panel controls and indicators. The specific controls and indicators
depend on the type and model of the storage devices used. Figure 1-2 shows the controls and indicators
typically found on HP supplied devices.
