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 controller 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.
