The appliance requires both InfiniBand and Ethernet (out-of band management) connectivity where eth0 should be connected to a management network switch, and both InfiniBand ports should be connected to InfiniBand switches. They can be connected to the same switch, but NVIDIA recommends connecting to two separate switches to ensure SM connectivity to the fabric.

Check to determine if your local or national electrical codes require an external ground to all IT components. If so, connect a ground wire to one of the casing screws and connect the other end to a valid ground. If you choose not to use the ground screw, make sure that the rack is properly grounded and that there is a valid ground connection between the chassis of the appliance and the rack. Test the ground using an Ohm meter.

The system is shipped with two power supply units. Each unit has a separate AC receptacle. The system accepts input voltages of 100 - 127 VAC and 200 - 240 VAC for all possible PS units. The power cords should be standard 3-wire AC power cords including a safety ground and rated for 15A or higher. The power supplies deliver 750W AC.
