I400C45 is the complete inference pack: eight A32 tanks, 400 kW, UPS + battery in the same 45 ft box. Up to 512 PCIe GPUs, PUE ≈ 1.05 on free-cooling climates. You land compute and power together. Expansion blocks: 90 days ex-works.I400C45 是完整的推理交付包：八个 A32、400 kW、UPS + 电池在同一具 45 英尺箱里。最多 512 张 PCIe GPU，自然冷却气候下 PUE ≈ 1.05。算力和电一起落地。扩容模块 90 天出厂（EXW）。
I400C45 is the published 400 kW immersion pack with power in the enclosure. 8× A32 tanks plus one 10 kW air rack, each tank to 50 kW with dual 2N CDUs, heat out on a 32/37 °C warm-water loop, EATON UPS and battery in the dedicated 45 ft power bay. On site you connect utility, water, and network — not a second power project.I400C45 是已发布的 400 kW 浸没包，电划进箱内。8 个 A32 加 1 个 10 kW 风冷柜，每舱最高 50 kW、双路 2N CDU，热量走 32/37 °C 温水回路，EATON UPS 和电池在 45 英尺独立配电舱。现场接市电、水和网——不是再做一套配电工程。
I400C45SUT50 (I400C45)Roadmap A separate MDCX power module (UPS / battery / PDC) is in development for sites where the boundary must sit outside the compute enclosure.面向必须把边界划到算力箱体之外的场地，MDCX 独立电源模块（UPS / 电池 / PDC）正在开发中。
IT Load vs. Facility Load. 400 kW is what the servers draw. Total facility load is ~440–500 kW once cooling and auxiliaries are added — the gap is set by PUE, which depends on your site's climate. *Sites whose historical peak dry-bulb stays ≤ 24 °C run on pure dry coolers (free cooling, lowest PUE); hotter sites add a hybrid chiller. Always confirm which figure an "X MW" requirement refers to. IT 负荷与设施总负荷。400 kW 指服务器实际用电。计入冷却与辅助系统后， 设施总负荷约为 440–500 kW——差值由 PUE 决定，而 PUE 取决于站点气候。 *历史极端干球温度 ≤ 24 °C 的站点可纯靠干冷器运行（自然冷却，PUE 最低）； 更热的站点需加装混合冷机。遇到「X MW」的需求时，务必确认指的是哪一个口径。
Pick I400C45 when the pad has no UPS of its own and lithium in the enclosure is allowed. You are buying one SKU instead of a compute box plus a yard power project. I400C40 is the twin that drops the power bay and five feet. I200C20 is the 20 ft, four-tank edge bay.场站没有自己的 UPS、且允许锂电池进箱时，选 I400C45。你买的是一个 SKU，不是一个算力箱再加一套场地配电。I400C40 是去掉配电舱和五英尺的双生。I200C20 是 20 英尺、四舱的边缘舱。

Both containers share the identical immersion core — 8× A32 tanks, the same oil loop, the same cooling rules. They differ in where the UPS lives. 两台集装箱共用完全相同的浸没核心——8 个 A32 液舱、同一条油回路、 同一套冷却规则。区别只在于 UPS 装在哪里。

Redundancy model. The container is the smallest redundancy unit: tanks are 2N on cooling internally, a single container has no internal IT redundancy, and system-level N / N+1 / 2N is built by adding containers. 冗余模型。集装箱是最小的冗余单元：液舱内部冷却为 2N， 单台集装箱内部不设 IT 冗余，系统级 N / N+1 / 2N 通过增加集装箱数量实现。
