Power module assembly
The Dell PowerEdge XR4000r a power module assembly which consists of two power distribution board (PDB's) and are
connected to each other so either or both power supplies can power the whole chassis. The power distribution board (PDB) at
the bottom also has chassis manager board to manage the chassis and the optional witness sled. The witness sled fan module is
mounted on the PDB which helps in cooling the witness sled. It also has two power interpose board (PIB) which provide power
to the sleds.
