When getting your head around networking in HyperV the first time, I find it helpful if your network cards are different manufacturers. Now in real life this is nearly impossible as the Quad card on most servers means all 4 are the same name. That said as others have pointed out, even on a production box you can throw in a more generic network card for the management role so you can more easily know which nic is which.
And do you have iLos or Drac cards too? Even the HP microserver comes with the ability to purchase a $80 remote access card to the hardware. This is a card that will let you get to the base hardware even if the OS doesn’t boot.
