[USRP-users] N310 schematic don't show all part

The N310 motherboard does not have a PCIe interface, proprietary or
otherwise.  Schematic p. 20 was a PoE controller on earlier, unreleased
versions of the N310, but it was omitted because it could not source enough
current to the device when both RF daughtercards were enabled.   The PoE
components were not populated on earlier module revisions and have been
eliminated entirely from recent revisions of the motherboard PCB.

Marcus is correct that several pages of the X310 schematic featuring the NI
PCIe ASIC were redacted because NI never authorized them for public release.
