Hot-Plug Disk Drive Indicators

The hot-swap disk drives have two LEDs per drive, as described below.
• Drive Status LED - The drive status LED is tri-color and may display green, amber, or yellow at any given time. These
colors indicate a normal, warning, or failure condition.
• Drive Activity LED - The drive activity LED is green and indicates disk drive activity. This LED is controlled by the disk
drive directly and turns on when a drive is accessed.

The power switch turns the HP Server power on or off. If sleep states are available, it
also transitions 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 Interface)
standard.
Press the nonmaskable interrupt (NMI) switch before restarting the system after a hung
condition occurs. NMI provides crash dump capture capability. Obtain a system
hardware status dump to use in root cause analysis and debugging.
