Power Up Test Sequence
During the initial power up phase, the system board checks the internal operating
voltages. By observing certain conditions, it is possible to gain an initial indication of the
power status of the system. By following the observations below, initial fault diagnosis may
be undertaken.
x Check audible power up beep from system.
Caution is to be taken here as many people mistake the beep emitted by bar code
scanners to be the system beep. To be 100% certain, power down the system,
remove the bar code scanner and then re-test.
x Check the two CPU cooling fans and the system fan are working correctly.
This can be done without removing the case as the airflow can be felt by putting your hand
near the ventilation ports.
x Check the System fan is operative.
This can be done without removing the case as the airflow can be felt by putting your hand
near the ventilation port on the rear of the unit. The fan however might not be operating if
the system temperature is low. In order to check the operation of this fan, run the Retail
Blade™ into the diagnostics program and alter the fan speeds to maximum. If they are still
not running when this is done, there may be a problem.
x Check external power supply fan is operative.
x Check HDD spins up to constant RPM.
It is also worth noting if any unusual sounds are heard while the HDD spins up to speed. If
any repetitive grinding or metallic knocking sounds are observed, the HDD may have a
problem.
x On the front panel, check the correct LED is lit.
In standby mode, the Green LED should be the only one on. When the unit is
powered on, the red power LED and the Green standby LED should be on.
x On the front panel, check red LED is flashing as the HDD is accessed.
x On the external PSU of DigiPoS, the power switch is illuminated.
x The memory check completes, without error before the operating system call
is initiated.
At this point the system should exit the primary boot stage and allow the system to be
controlled by the user software such as Windows or Linux.
If this does not occur, record at which point the power up sequence fails and proceed to
the next section.
