Light Path
Diagnostics
Look at the system service label on the top of the server, which gives an
overview of internal components that correspond to the LEDs on the light path
diagnostics panel. This information and the information in “Light path diagnostics
panel” can often provide enough information to correct the error.
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:
v
All known errors are corrected.
v
The server is restarted.
v
A new error occurs, causing the system-error LED to be lit again.
Light path diagnostics panel
The following table lists the LEDs on the light path diagnostics panel, the problems
that they indicate, and actions to solve the problems.
v
Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See the parts listing in the Problem Determination and Service Guide to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
