There is a non-redundant and redundant version of the power supply system：
Non-Redundant Power:
With this implementation, a Chassis Series-A power supply module slides onto the left side of the chassis. This connects the DC output voltage to the chassis backplane and powers all modules that are inserted into one of the chassis slot positions. There is a version that accepts AC source power and a version that accepts DC source power.
Redundant Power:
With this implementation,n panel-mounted Chassis Series-A power supplies are connected to the chassis through a chassis adaptor module that connects to the left side of the chassis. If one power supply fails, the other will carry the load. There is a version that accepts AC source power and a version that accepts DC source power.
PMIO Power System Redundancy:
The PMIO platform provides a fully redundant and robust power supply assembly. This supply generates 24 Vdc and can be used as the source power for a DC-type Chassis–A power supply.
Redundant Power System Versions:
There are two versions of the redundant power system. They differ by the cables and chassis adaptor (power supplies are the same). Older versions may exist in the field, but they are no longer available for sale. The table below shows the old and new versions and associated model numbers.
