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.

Compute Tray: Power Delivery

Evidence

This differs from Grace Blackwell, where 50VDC power goes directly to the PDB

Context After

② Atomic Claim

這與 Grace Blackwell 不同，後者的 50VDC power 直接送入 PDB。

⑤ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
