IBM 201 Appendix C. Engine POST messages, Power-on self-test POST, POST beep code descriptions

Appendix C. Engine POST messages

This appendix identifies and describes POST messages that you might encounter, and gives corrective actions where applicable.

Note: The information in this appendix applies to each engine in the appliance. For example, when the text reads, “When a monitor and keyboard is attached to the appliance,” that means that a monitor and keyboard has been attached to either of the two engines.

Power-on self-test (POST)

When you turn on your NAS 200, its engine performs a power-on self-test (POST) to check the operation of appliance components and some of the options installed in the appliance.

If POST finishes without detecting any problems when a monitor and keyboard are not attached to the appliance, you will hear one long and three short beeps. When a monitor and keyboard are attached, you will hear one short beep. Any other series of beeps indicates a problem, and an error message appears on your screen. See “POST beep code descriptions” for more information.

Notes:

1.If you have a power-on password or administrator password set, you must type the password and press Enter, when prompted, before POST will continue.

2.A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the test.

POST beep code descriptions

Beep codes are sounded in a series of beeps. For example, a 1-2-4 beep code sounds like one beep, a pause, two consecutive beeps, another pause, and four more consecutive beeps.

The possible types of beep codes that your appliance might emit include the following:

No beeps

If no beep occurs after your appliance completes POST (that is, after the system POST complete (OK) light on the operator information panel is illuminated), call for service.

Continuous beep

The recovery enablement disk has booted, your startup (boot) microprocessor has failed, or your system board or speaker subsystem might contain a failing component. If the system continues through POST with no errors, call for service. If no video appears, the startup processor has failed; replace the startup processor.

One short beep

When a monitor and keyboard is attached to the appliance, one beep indicates that your appliance successfully completed POST. POST detected no configuration or functional errors. One beep also occurs after your appliance completes POST if you enter an incorrect power-on password.
