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

press the button. The reset button is in the lower-right corner of the light path
