PMP20859: Disabling TPS2372 PoE controller completely.

Part Number: PMP20859
Other Parts Discussed in Thread: TPS2372

We have successfully implemented a dual PoE & external 48V input based on the PMP20859 reference circuit, which works fine. External 48V in only, works. PoE swapping over works no glitches, all fine.

In our next design we need the same again but the need the ability to disable one of the PoE power inputs, so that it its just plain 1G Ethernet.

Do we just pull the DEN pin low on the TPS2372 to completely disable it and prevent it taking part in any power control and Ethernet configuration messaging ?
