The following illustration shows the LEDs and controls on the light path
diagnostics panel.
v Remind button: This button places the system-error LED on the operator
information panel into Remind mode. In Remind mode, the system-error LED
flashes once every 2 seconds until the problem is corrected, the server 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.
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 in the lower-right corner of the light path
diagnostics panel.
