Light Path Diagnostics

Reset button

vRemind button: This button places the system-error LED on the front 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. The remind function is controlled by the IMM.

vNMI button: Press this button to force a nonmaskable interrupt to the microprocessor, if you are directed to do so by IBM service.

vReset 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.

For more information about light path diagnostics, see the Problem Determination and Service Guide on the IBM Documentation CD.
