Table 1-1. Control Panel Switch and Indicators

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.
