LSS7C06HX6S0 FAQ
Q1: Is this power module compatible with the Huawei S6720-50L-HI switch? Does dual-mode switching require manual configuration?
A1: Fully compatible! No manual configuration is required. It automatically identifies the power supply type after plugging in AC or DC power, making it plug-and-play and compatible with the switch's native power supply logic.
Q2: Can the 1600W power supply simultaneously power one mid-range switch (400W), two mini servers (300W/unit), and three monitoring devices (100W/unit)? Is it sufficient in redundancy mode?
A2: Absolutely sufficient! The total power is approximately 1300W, lower than the 1600W rated value, providing ample redundancy. In 1+1 redundancy mode, a single module failure can independently handle the entire load, ensuring stable and stress-free power supply.
Q3: What are the core differences between this module and the Huawei W2PSD2200 (2200W dual-mode)? How should small and medium-sized enterprises choose?
A3: The core differences lie in power and cost: The ES02PSD16 (1600W, high cost-performance) is suitable for small to medium loads and budget-constrained scenarios; the W2PSD2200 (2200W, high power) is suitable for high load scenarios. For 15 or fewer mid-range devices, the mid-range dual-mode model is more cost-effective.
