Beep code descriptions

Use this information to determine beep codes and how to resolve the error.

The following table describes the beep codes and suggested actions to correct the detected problems.

A single problem might cause more than one error message. When this occurs, correct the cause of the first error message. The other error messages usually will not occur the next time POST runs.

Exception: If multiple error codes or light path diagnostics LEDs indicate a microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See Microprocessor problems for information about diagnosing microprocessor problems.
  • Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
  • See Parts listing, Types 8014, 8028 and 1916 to determine which components are CRUs and which components are FRUs.
  • If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician.
