Using light path diagnostics to identify system errors

About this task

If an error occurs, view the light path diagnostics LEDs in the following order:

Procedure

  1. Look at the operator information panel on the front of the server. Check if the information LED or system error LED lights up.
  2. View the light path diagnostics panel. Lit LEDs on this panel indicate the type of error that has occurred.
    ImportantImportant

    The checkpoint code display does not provide error codes or suggest components to be replaced. The checkpoint code is an internal code used for IBM development only and is subject to change over time. Ignore this code unless you have a specific request from Avaya to note it.

  3. Remove the server cover while the server is connected to power and look inside the server for lit LEDs.
    ImportantImportant

    Always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server. For more information, see Protecting against ESD damage.

    Certain components inside the server have LEDs that light up to indicate the location of a problem. For some components, such as dual inline memory modules (DIMMs) and fans, these LEDs can help you identify the problem. For other components, these LEDs are not useful.

    Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped, which means that you can remove or install the component while the server is running. Orange can also indicate touch points on hot-swap components. See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.
