Gateway 4 can be powered from either an external PSU (9-48 VDC) or with PoE. The latter requires a suitable Ethernet switch for the power source.
Please reference wiring instructions if using external PSU. Gateway 4 is not compatible with Zero 88’s legacy console PSUs.
Please note that the product should be powered via EITHER the DC power input or Ethernet PoE, but not both (there is no option to fail-over from one power source to the other if both are connected).
