System ID Blue This LED is located on the Main Board and is visible through
holes in the rear panel. It can provide a mechanism for
identifying one system out of a group of identical systems.
This can be particularly useful if the server is used in a rack-
mount chassis in a high-density, multiple-system application.
The LED is activated by depressing the front panel System ID
pushbutton or if the server receives a remote System Identify
command from a remote management console. If activated
by the front panel pushbutton, the LED remains on until the
pushbutton is depressed again. When the LED illuminates
due to a remote System Identify command, the LED turns off
after a timeout period. An additional blue System ID LED is
located on the front panel that mirrors the operation of the
rear Main Board LED.
System Status/Fault Green/Amber This LED reflects the state of the System Status LED on the
front panel.
Power Supply Green/Amber This is a bi-color LED that can be on, off, green, amber, or
blinking, or combination thereof. See “Rear Panel Power
Supply Status LED” on page 2-20 for more detailed
information.
