Compact FieldPoint power supply

[DtHarry]

I have a cFP-1804 network module for and one 24V-5A QUINT POWER supply for my project. A cFP-DI-304 Digital input will be connected to the network module backplane, of course with its connector block. Does the power supply powers up the complete netowrk module with the digital I/O module(s) connected to the backplane? or the power supply must also be connected to the digital module through its connector block? I expect that supplying power just to the network module is enough, but this is not very clear to me from the user manuals that come with the eqquipments.

I have a cFP-2120 controller with a cFP-DIO-550 and it was necessary to supply 24V power to the module as well.  But that was for the digital outputs.

I found the manual for the DI-304 on NI's site.    http://www.ni.com/pdf/manuals/374168a.pdf  It does not appear to require the voltage be applied to the module.
