Basic Installation Procedures : Connecting to a Power Source and Powering Up

Connecting to a Power Source and Powering Up
The OnBoard appliance comes with either one or two power supplies. When the OnBoard appliance has two power supplies, connect each power supply to a separate power source for redundancy in case one power source fails. The power sources must be independent of each other and must be controlled by separate circuit breakers.
