IBM System x3530 M4 26
Light path diagnostics panel
The light path diagnostics panel allows system engineers and administrators to easily and quickly
diagnose hardware problems on IBM System x servers. If a failure occurs, a light is illuminated on the
front panel of the server (level 1 light path) to alert the systems administrator that there is a problem. The
light path diagnostics panel (light path level 2) will have a light next to the LED for the failed subsystem.
This light directs the engineer or administrator to the failed component, also shows an illuminated LED
near it (light path level 3) (for example, the DIMM error LED on the system board).
x3530 M4 offers two variants of light path diagnostics: basic and advanced. All standard x3530 M4
models include basic functionality that provides light path levels 1 and 3. Advanced functionality is
optional; it contains a pop-out panel that adds light path level 2.
The following figures show the basic (level 1) and advanced (level 2) light path levels.
