Planning for power

Each enclosure is provided power through two power supplies. Either power supply unit can power the enclosure independently if there is a loss of input power to the other power supply in the enclosure.

Plan to connect the power cords of the power supplies on the left side of the enclosures (when viewed from the rear) to one power source, and the power cords of the power supplies on the right side of the enclosures to another power source.
Attention: The power cord is the main power disconnect. Ensure that the socket outlets are located near the equipment and are easily accessible.
