Power-on LED: This green LED is lit and stays on when you turn on your server
and flashes when the server is in Standby mode.
Attention: If the power-on light-emitting diode (LED) is off, it does not mean there
is no electrical current present in the server. The LED might be burned out. To
remove all electrical current from the server, you must unplug the server power
cords from the electrical outlets or from the uninterruptible power device.
Power-control button: Press this button to manually turn on the server and put the
server in Standby mode (see “Server power features” on page 9).
Reset button: Press this button to reset the server and run the power-on self-test
(POST). You might need to use a pen or the end of a straightened paper clip to
press the button.
SCSI or IDE bus activity LED: This LED is on when there is activity on the SCSI
or IDE bus.
System-error LED: This amber LED is lit when a system error occurs. An LED on
the diagnostic LED panel will also be on to further isolate the error.

drive is in use.

is in use.
