v Power LED: When this green LED is lit and not flashing, it indicates that the
server is turned on. When this LED is flashing, it indicates that the server is
turned off and is still connected to an ac power source. When this LED is off, it
indicates that ac power is not present, or the power supply or the LED itself has
failed. A power LED is also on the rear of the server.
Note: If this LED is off, it does not mean that there is no electrical power in the
server. The LED might be burned out. To remove all electrical power from
the server, you must disconnect the power cord from the electrical outlet.
v Power-control button: Press this button to turn the server on and off manually.
A power-control-button shield comes with the server. You can install this
disk-shaped shield to prevent the server from being turned off accidentally.

the SATA drive indicates hard disk drive activity is on the operator
information panel.

the Light Path diagnostics panel on the system board is also lit to help isolate the
error. This LED is controlled by the BMC.
