The Nodegrid unit can have one or multiple power supplies (AC or DC). Connect all the power supplies with appropriate cables to an available power source (usually a Rack PDU. If the unit was shipped with one power supply, that unit has no power failure redundancy. Units with two power supplies provide redundancy against power failures. Make sure these power supplies are connected to two independent power sources.
NOTE
On the Nodegrid Net Services Router with PoE support, the second power supply specifically powers the PoE feature – and does not provide power outage redundancy.
When all power supplies are appropriately connected to a power source, power can be turned on.
