Plug the other end of the power cables into a grounded electrical outlet or a separate power source
such as an uninterrupted power supply (UPS) or a power distribution unit (PDU). If possible, connect
the power supplies to two different 110V power sources or two different 220V power sources,
depending on the power supplies used.
Turning on the System and Monitor
Press the power button on the system and the monitor (optional). The power indicators should light.
