Appendix D. Engine POST and diagnostic program 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 Model 326, 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 set 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.
