1. A rack-level power infrastructure, comprising:
- a power distribution unit (PDU), wherein the PDU receives alternating current (AC) power from an external power source;
a busbar coupled to the PDU, wherein the PDU outputs direct current (DC) power to the busbar;
a detachable power cable interface box (PCIB) coupled to the PDU, wherein the PCIB comprises modular components that allow for the PCIB to receive multiple types of AC power without requiring a re-wiring of any connections to or from the PDU;
a first terminal within the PCIB for receiving one or more wires associated with the AC power;
a detachable interface coupled to the first terminal;
a swappable wiring block within the PCIB coupled to the first terminal, wherein the wiring block arranges one or more wires output from the first terminal into a pre-determined wiring arrangement for output to a second terminal within the PCIB, wherein the pre-determined wiring arrangement corresponds to a wiring arrangement of a third terminal;
at least one server coupled to and receiving DC power from the busbar; and
a battery back-up unit (BBU) element coupled to the busbar, wherein the BBU element charges from and discharges to the busbar and wherein the BBU comprises a connector card that couples with a card connector of the PDU.

Abstract
In accordance with the present disclosure, a scalable and modular rack-level power infrastructure is described. The power infrastructure may include a power distribution unit (PDU), which receives alternating current (AC) power from an external power source. The PDU may be coupled to a busbar and output DC power to the busbar. The busbar may be coupled to a server within a rack-server system and provide DC power to the server. Additionally, the infrastructure may include a battery back-up unit (BBU) element coupled to the busbar. The BBU element may charge from and discharge to the busbar.
