Light path diagnostics feature

On the BladeCenter system, the light path diagnostics feature consists of the LEDs on the front and rear of the BladeCenter chassis and on the front of the modules and blade servers. If the system-error LED on the system LED panel on the front or rear of the BladeCenter unit is lit, one or more error LEDs on the BladeCenter components also might be on. These LEDs help identify the cause of the problem.

Identifying problems using the light path diagnostics feature

This section provides the information to identify, using the light path diagnostics feature, problems that might arise during installation.

To locate the actual component that caused the error, you must locate the lit error LED on that component.

The following example illustrates how to use the light path diagnostics feature to diagnose a system error:

1.Note that the BladeCenter system-error LED is lit on the system LED panel.

2.Locate the module or blade server that also has an error LED lit (see “BladeCenter components, controls, and LEDs” on page 31 for the location of error LEDs; see the documentation that comes with your blade server for the location of error LEDs on the blade server).

a.If the component is a module, replace the module.

b.If the component is a blade server with its system error LED lit, follow the instructions in the documentation that comes with the blade server to isolate and correct the problem.
