PDU Function
The PDUs provide connections for the DC power cables, circuit breakers, and over current
protection; configure the output voltages produced by the power supply modules into
three different output zones; and connect to the midplane, which distributes the different
output voltages to the packet transport switch components, depending on their voltage
requirements.
