Rack AC Power Distribution
The power distribution configuration in a Rack System/E rack depends on the
number of storage systems installed in the rack. If one storage system is installed,
only two PDUs are required. If multiple storage systems are installed, four PDUs
are required.
The site AC input voltage is routed to each PDU mounted in the rack. Each PDU
distributes AC through ten receptacles directly to the storage system components.
■ PDUs 1 and 3 (optional) are mounted on the left side of the cabinet. Grey
power cords connect these PDUs to the number 1 drive enclosure power
supplies and to the controller enclosures.
■ PDUs 2 and 4 (optional) are mounted on the right side of the cabinet. Black
power cords connect these PDUs to the number 2 drive enclosure power
supplies and to the controller enclosures.
