Description

Blue and amber

system status

indicator

The blue system status indicator lights during normal system operation. The amber system status indicator flashes when the system

needs attention due to a problem with power supplies, fans, system temperature, or hard drives, or if a chassis intrusion is detected.

NOTE: If the system is connected to AC power and an error has been detected, the amber system status indicator flashes regardless

of whether the system has been powered on.



NOTE: Use the systems management software to manage chassis intrusion alert actions and reset the system to detect future

security breaches.

Power button

l If you turn off the system using the power button and the system is running an ACPI-compliant operating system, the system

can perform an orderly shutdown before power is turned off. If the power button is pressed for more than 4 seconds, the

system power will turn off regardless of the current operating system state.

l If the system is not running an ACPI-compliant operating system, power is turned off immediately after the power button is

pressed.

The power button is enabled in the System Setup program. When disabled, the button can only turn the system power on. For more

information, see "Using the System Setup Program" in your User's Guide, and the operating system's documentation.
