Planning for power

Plan to attach each of the two power supplies in an enclosure to separate main power supply lines.

Attention: The power cord is the main power disconnect. Ensure that the socket outlets are located near the equipment and are easily accessible.

For more information about NEBS-compliant installations, see NEBS-compliant earth connection and Configuring a Storwize V3700 system to be NEBS-compliant.

Storwize V3700 models are available for use in AC power environments and in DC power environments. For a list of models, see Reviewing your packing slip.

In AC power environments

Plan to attach each of the two power supplies in an enclosure to separate main power supply lines.

Attention: The power cord is the main power disconnect. Ensure that the socket outlets are located near the equipment and are easily accessible.

Plan to connect the power cords of the auto-sensing power supplies on the left side of the rack (when viewed from the rear) to one power source that provides power in the range 100 V - 240 V AC. Plan to connect the power cords of the power supplies on the right side of the rack to another 100 V - 240 V AC power source. Using two power sources provides power redundancy. The power cords also provide a connection to the earth terminal of the socket outlets.

In DC power environments

Refer to Direct current power supply units for information about installation in DC power environments.
