Q-SYS NV-32-H network video endpoints do not ship with a physical power supply. The NV-32-H can be powered via generic 48vDC 2.0A power supply. Alternatively, the NV-32-H supports the 802.3bt Type 4 specification for Power Over Ethernet (PoE) via its LAN A connection.
POE90U-1BT6 is a midspan injector that will provide the necessary power.
