Context Before

At the compute tray level, 50VDC power enters the compute tray via the busbar clips at the back of the chassis. Then power travels to the middle of the chassis via the internal busbar cables. From the internal busbar cables, the power path is split into three destinations.

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.

Context After

The third path goes to the power distribution module at the front of the chassis.

② Atomic Claim

第一、第二條 path 分別前往左、右 Strata Board，由內部 busbar cable 直接供應 50VDC power。
