Standby Power System
Dell EMC Unity systems are powered by 2 power supplies (PS) per DPE/DAE. Each power supply can provide
power to the entire module if the peer PS has been removed or is faulted. DPE power during a power failure is
provided by a Battery Back Up (BBU) module. BBU is located within the SP enclosure and provides power to a
single module (power zone)
