Diagnostics: Device Test
This screen shows the results of the Power-On Self Test, which is automatically run when the
VBrick is reset or powered on. Other than that, running this test allows the operator to test
the hardware integrity of the VBrick appliance board by running the test one or more times
or by setting the test for continuous operation or for a certain number of test loops. This test
is not often used. It is necessary to be in Diagnostic mode before running these tests. Enter
Diagnostic mode from the Configuration > System screen. Don't forget to return to Run
mode after the tests are run. You must be in Edit mode before you can run this test. Test
Results include Pass, Fail, Not Present. Note that depending on the model, a low intensity
test sequence may take 5-15 seconds per test sequence; a high intensity test sequence can take
5-15 minutes or more.
