Rack System/E power distribution components

AC power is distributed to the Rack System/E rack through Power Distribution Units (PDU) mounted
on the two vertical rails in the rear of the rack. Up to four PDUs can be mounted in the rack—two
mounted on the right side of the cabinet and two mounted on the left side.
Each of the PDU power cables has an AC power source specific connector. The circuit
breaker-controlled PDU outputs are routed to a group of ten AC receptacles. The storage system
components plug directly into the PDUs.

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.
