Planning for power for server canister
Each enclosure is provided power through two power supplies. Either of the 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 connect 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.
Figure 11 on page 26 shows the back of a Elastic Storage System 3000. Each PSU is located on the sides
of ESS 3000.
