MaxiLife Test Sequence and Error Messages
Diagnostics
Runs a set of diagnostics assessing the system's components. Results of the tests are
displayed on the LCD status panel, one after another when the LCD buttons are
pressed.
For MaxiLife to access the status of some of the components, the power supply has to be in
the ON state. If the system is turned off when Diags is launched, a menu will be displayed,
requesting an authorization to power on the Personal Workstation. It is possible to cancel
the diagnostic process and return to the previous state by pressing the LCD key labelled
"Back". When "GO" is selected, the main power supply is started but the Personal
Workstation is not allowed to do a normal boot. The purpose of this is to allow only these
devices that can be tested to answer the diagnostic request from MaxiLife.
Components are tested in sequence when the "Next" button is pressed. When they have all
been checked, a diagnostic screen is shown. Depending on the result of the diagnostics, the
screen could indicate either:
OK or FAIL.
At the end of the test, you can exit the diagnostic mode by pressing the LCD button. If
the power supply was off when the diagnostics was started, it will be turned off again.
The following diagram shows how the "Power On" is activated when the main power
supply of the Personal Workstation is turned off.
