power distribution units (PDUs)
A Power Distribution Unit (PDU) is equipment located in or near a
computer room which breaks down electric power from a high-voltage
source to appropriate levels of distribution to the central processing unit
and peripheral devices of a computer system. Figure 1-1 shows an
example PDU that is used with the HP product racks. This example is
the HP E7674A 16 Amp 100-240VAC PDU (part number A5137AZ).
CAUTION Some components have been designed to be used with specific electrical
accessories such as PDUs. The use of any accessory other than those
specified is neither recommended nor supported.
