Path Diagnostics panel, followed by a description of the buttons and each LED.
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 and
just above the small circle with the R inside.
v
Light Path diagnostic LEDs: You can slide out the operator information panel
and drop it down for easy viewing without opening the top server cover. The
LEDs are on the top of the operator information panel.
The following table lists the LEDs and the problems that they indicate.
