Power input module

A method comprising:

• utilizing, by an input power line transfer switch circuit of a module, a first input power connector of the module as a power provider to an output power cable of the module, wherein a first input power cable is connected to the first input power connector of the module;
• in response to an input power line switchover event, switching, by the input power line transfer switch circuit of the module, the power provider to the output power cable of the module from the first input power connector of the module to a second input power connector of the module, wherein a second input power cable is connected to the second input power connector of the module;
• and
• providing, by an energy storage component of the module connected to an output power connector of a system, power to the system in response to a power supply failure.

A system comprising:

• at least two bays to accept power supply units;
• and
• a hot pluggable redundant power input module pluggable into the bays, the hot pluggable redundant power input module comprising:
• a first input power connector and a second input power connector;
• an input power line transfer switch circuit to connect one of the first input power connector and the second input power connector to an output power connector based on a power event;
• an energy storage component to connect to a hot plug output power connector.
