Description
The power-on indicator lights when the system
power is on. The power button controls the power
supply output to the system.
NOTE: On ACPI-compliant operating systems,
turning off the system using the power button
causes the system to perform a graceful
shutdown before power to the system is
turned off.
Used to troubleshoot software and device driver
errors when running certain operating systems.
This button can be pressed using the end of a
paper clip.
Use this button only if directed to do so by
qualified support personnel or by the operating
system's documentation.
The identification buttons on the front and back
panels can be used to locate a particular system
within a rack. When one of these buttons is
pressed, the LCD panel on the front and the
system status indicator on the back flashes until
one of the buttons is pressed again.
Press to toggle the system ID on and off.
