v
Remind button: This button places the system-error LED on the front panel into
Remind mode. In Remind mode, the system-error LED flashes rapidly until the
problem is corrected, the system is restarted, or a new problem occurs.
By placing the system-error LED indicator in Remind mode, you acknowledge
that you are aware of the last failure but will not take immediate action to correct
the problem. The remind function is handled by the BMC.
v
Reset button: Press this button to reset the server and run the power-on
self-test (POST). You might have to use a pen or the end of a straightened paper
clip to press the button. The reset button is to the right of the remind button.
For information about light path diagnostics, see the System x3550 Problem
Determination and Service Guide on the IBM System x Documentation CD.

both the ac and dc power LEDs are lit. For any other combination of LEDs, see
the Problem Determination and Service Guide on the IBM System x
Documentation CD.
