The Huawei CloudEngine S8700-10 is a high-performance aggregation switch designed for enterprise campus networks. It supports up to 4 power modules , which provide redundancy and ensure stable operation even in the event of a power module failure. Redundant power supplies are critical for maintaining network uptime and reliability, especially in mission-critical environments.

The other options (2, 6, and 8) do not match the specifications of the S8700-10. While some models in the S8700 series may support fewer or additional power modules, the S8700-10 specifically accommodates up to 4 power modules.
