3.3 How to change and insert the video interface modules
These modules are fixed with two screws. To change a module it is only
necessary to release both screws and carefully withdraw the module.
Take care when installing a module that the board is supported on the
guiderails at each side, and insert the module precisely in the straight or
horizontal position until the connector engages.
 Always shut the power off before changing modules!

3.4 Power supply and switch contact
To activate the VX-HDV-IP a 12VDC/2A power supply is required.
The two separate power input connections on the back allow for a redundant
power supply. If you only use one power supply, you can connect it to either
of these inputs.
The switch contact is for monitoring the two power inputs. It closes in order to
signal any power failure, for example to a control system.
