operator panel to the left. Pull forward on the panel until the hinge of the
operator panel is free of the server chassis. Then pull down on the panel so
that you can view the light path diagnostics panel information. This reveals the
light path diagnostics panel. Lit LEDs on this panel indicate the type of error
that has occurred.
Note: When you slide the light path diagnostics panel out of the server to
check the LEDs or checkpoint codes, do not run the server continuously with
the light path diagnostics panel outside of the server. The panel should only be
outside of the server a short time. The light path diagnostics panel must remain
in the server when the server is running to ensure proper cooling.
The following illustration shows the light path diagnostics panel:
Note any LEDs that are lit, and then reinstall the light path diagnostics panel in
the server.
v Remind button: Press this button to place the system-error LED on the front
information panel into Remind mode. 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. In Remind
mode, the system-error LED flashes rapidly until one of the following
conditions occurs:
– All known errors are corrected.
– The server is restarted.
– A new error occurs, causing the system-error LED to be lit again.
v NMI button: The NMI button on the front panel will come on when this
button is pressed. Press this button to force a nonmaskable interrupt to the
microprocessor. You might have to use a pen or the end of a straightened
paper clip to press the button. It allows you to blue screen the server and
take a memory dump (use this button only when directed by the IBM service
support).
