Context Before

For the modules at the front of chassis—CX-9, BlueField-4, and management—the PDB feeds 12VDC of power to each of the modules.

Evidence

50VDC is stepped down to 12VDC at the PDB then, via a copper busbar device, the PDB feeds 12VDC to its neighboring modules.

Context After

The power connector of CX-9 is located near the Paladin HD2 at the top of the modules.

② Atomic Claim

PDB 先將 50VDC 降至 12VDC，再透過 copper busbar device，向鄰近 modules 供應 12VDC。
