Context Before
Previously, cold plates were assembled at the L10 assembly level where the various components are put into place in the chassis. Given the modular approach, the cold plates need to be more tightly integrated with the module itself. Hence, the cold plate will be attached at the L6 assembly level right after the PCBA process. This increases the assembly efficiency as the assembly at L10 is simplified to slotting in the completed modules into the corresponding connectors and quick disconnects.

Evidence
The first and second path goes to the left and the right Strata Board, where the internal busbar cable feeds 50VDC power to the Strata Board directly
