Overview
There are two groups of diagnostics: Low Level Hardware Diagnostics and User Diagnostics.
Low Level diagnostics are run in Diagnostics mode. User diagnostics are run in normal Run
mode. (The Configured Operational Mode is set in Configuration: System as described below.)
You must be in
Diagnostics mode to run Hard Drive Check Disk and Device Test POST
Tests. You can run all other tests from Run mode.
T To change between normal Run mode and Diagnostics mode
1. Log in with Administrator or Operator Privilege. The default login Username and
Password is
admin/admin or operator/operator (case sensitive).
2. Go to the
Configuration: System screen.
3. Click
Begin Edit.
4. Set
Configured Operational Mode as required.
5. Click
Apply Changes.
6. The VBrick will then automatically save the changes and reset.
Low-Level Hardware Diagnostics
These are tests that test the hardware integrity of the VBrick appliance board and are not
often used. If they are necessary, the tests can be set for continuous operation or for a certain
number of test loops, and run at low or high intensity. 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.
User Diagnostics
There are three user diagnostics: Network Test, Device Test, and Decoder Color Bar.
Note Since running in
Diagnostics mode interrupts the passing of video, be sure to return
the appliance to the
Run mode in order to return the appliance to its normal
operational state.
