@mldowling, @rocknolds, you may refer to the pictures below of the outcome of the mentioned scenario. Hope it helps.
Scenario - A: 52V (or 48V) Terminal Block Power Input:
-
LAN Port #1 - PoE Output => YES

-
LAN Port #2 - PoE Output => YES

-
WAN/LAN Port #3 - PoE Output => YES

Scenario - B: 802.3at Power Input from SD-Switch (White Cable):
- HD2 Mini => No Power (it needs Passive PoE)
- LAN Port #1 & #2 - PoE Output => NO

[Update on 07 November 2019, as highlighted in this post]
The recommended power input range that enables the PoE Out is 48-56VDC.
