Huawei’s ECC800-Pro supports PUE (Power Usage Effectiveness) management as part of its energy efficiency and green data center features. In practical O&M, different sites calculate PUE differently depending on metering topology, what loads are included (IT load only vs. auxiliary loads), and whether the site uses integrated modules (UPS, cooling, lighting, etc.) or external systems. To handle these real-world differences, the ECC800-Pro provides two PUE configuration approaches on the WebUI.“Standard”mode is used when the site’s metering points and calculation logic align with a predefined Huawei template, enabling rapid commissioning and consistent reporting.“User-defined”mode is used when the customer’s metering structure or management requirements differ—allowing engineers to select specific measurement points, define inclusion/exclusion rules, and tailor the calculation path so that displayed PUE matches the site’s accepted KPI definition. This dual-mode design ensures PUE is both standardized where possible and flexible where necessary, improving energy analysis accuracy and supporting optimization actions.
