DC Power Distribution Unit
The Power Distribution Unit (PDU) supplies redundant power to components in the MPS cabinet (for
example, IBM servers and VRC chassis) that do not have their own redundant power supplies.

DC Fuse Panels and Circuit Breaker Panels
There are two types of fuse panels for DC power distribution; one with fail over capability and one
without fail over capability. The fuse panel with fail-over capability is for servers without dual power
supplies. The fuse panel without fail-over capability is for servers with dual power supplies, such as
the x3550 the Netra 240.
