Engine troubleshooting and diagnostics

This section gives troubleshooting information for the IBM 5187 Network Attached Storage Model 6RZ (engine).

Engine diagnostic tools overview

The following tools are available to help you identify and resolve hardware-related problems:

vPOST beep codes, error messages, and error logs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem. See “Power-onself-test (POST)” on page 87 for more information.

POST error messages and descriptions are given in “Appendix C. Engine POST messages” on page 87.

vDiagnostic programs and error messages

The diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of your appliance. See “POST diagnostic programs” on page 97 for more information.

vLight-path diagnostics

Your appliance has light-emitting diodes (LEDs) to help you identify problems with appliance components. These LEDs are part of the light-path diagnostics that are built into your appliance. By following the path of lights, you can quickly identify the type of system error that occurred. See “Light-path diagnostics” on page 50 for more information.

vIntel® PROSet II

See “Testing the Ethernet adapters with Intel PROSet II” on page 65.

vTroubleshooting charts

These charts list problem symptoms, along with suggested steps to correct the problems. See “Engine troubleshooting charts” on page 52 for more information.
