Release button
To access the optional advanced light path diagnostics panel, push the blue release button on the advanced
operator information panel. Pull forward on the unit until the hinge of the operator panel is free of the server
chassis. Then pull down on the unit, so that you can view the light path diagnostics panel information.
Note: When you slide the optional advanced light path diagnostics panel out of the server to check the
LEDs, do not run the server continuously with light path diagnostics panel outside of the server. The panel
should only be outside of the server a short time. The optional advanced light path diagnostics panel must
remain in the server when the server is running to ensure proper cooling.
The following illustration shows the LEDs and controls on the light path diagnostics panel.
• Remind button: This button places the system-error LED on the front information panel into Remind
mode. In Remind mode, the system-error LED flashes every 2 seconds 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 controlled by the IMM2.
• 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.
