Power On-Self Test (POST) Errors
Power On-Self Test (POST) Errors
Should the POST encounter a problem, the single beep will be followed by a
combination of long and short beeps detailed in the table below. There is little
difference between a short and long beep, you may have to hear the beep code
several times to interpret it.
In addition to multiple beeps, the Operator LED blinks Red once every four
seconds. All POST errors are considered fatal and will prevent the WS4 from
booting to WinCE.
How the WS4 behaves after encountering the POST error depends on the boot
loader version. The boot loader version can be determined by checking the
System Information screen in the WS4 Diagnostics Utility.
If the POST in Boot Loader V2.0.08 or earlier encounters an error, the beep
code sounds once, the WS4 halts and does not respond to the power button.
You must remove, then reconnect the AC power cable to restart the unit.
If the POST in Boot Loader V2.0.09 or later encounters a problem, the error
code sounds three times and halts, but the WS4 responds to the power button.
Please note that WS4 Diagnostic Utility versions prior to 1.87 do not display
the Boot Loader version correctly. For example, Boot Loader version 2.0.08 is
incorrectly reported as version 2.08.
