IBM Distributed Power Interconnect (DPI) high density power distribution unit
Some PDUs are mounted sideways beside the rack space. The cluster supports
rack PDUs and front-end PDUs. The cluster can have the PDUs installed in the
side pockets and not accessible from the rear. Some of the newer cluster
configurations provide access to the PDUs from the rear of the system cabinet.
Rack PDUs provide power to components within a cabinet; front-end PDUs provide
the connection to the external power source and distribute the power among the
rack PDUs. To eliminate the need for the front-end PDU, a rack PDU is directly
connected to the external power source. Up to four front-end PDUs and up to 12
rack PDUs can be placed in each cabinet.
DANGER
The breaker switch on the PDU is not accessible. To turn off power to the
cabinet, you must disconnect all the PDU power cords from the electrical
outlets or from the individual PDU inlets.
