To access the light path diagnostics panel, slide the blue release button on the
operator information panel to the left. Pull forward on the operator information panel
until the hinge of the panel is free of the server chassis. Then pull down on the
operator information panel, so that you can view the light path diagnostics panel
information.
Notes:
1. Do not run the server for an extended period of time while the light path
diagnostics panel is pulled out of the server.
2. Light path diagnostics LEDs remain lit only while the server is connected to
power.
The following illustration shows the controls and LEDs on the light path diagnostics

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 iBMC.
v NMI button: Press this button to force a nonmaskable interrupt to the
microprocessor, if you are directed to do so by IBM service.
v
Checkpoint code display: This display provides a checkpoint code that
indicates the point at which the system stopped during the boot block and POST.
A checkpoint code is either a byte or a word value that is produced by UEFI. The
display does not provide error codes or suggest components to be replaced.
