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.
