3.6.2 Remind button
You can use the remind button on the light path diagnostics panel to put the system-error LED
on the operator information panel into Remind mode. When you press the remind button, you
acknowledge the error but indicate that you will not take immediate action. The system-error
LED flashes while it is in Remind mode and stays in Remind mode until one of the following
conditions occurs:
All known errors or suboptimal conditions are corrected.
The server is powered back on.
A new error or suboptimal condition occurs, causing the system-error LED to be lit
again.
You can also use the remind button to turn off the LOG LED on the light path diagnostics
panel and the information LED.
In multi-node configurations, you can also press this button during startup to start the server
as a stand-alone server.
