S5731-S32ST4X-A Overview The Cloud Engine S5731-S series switches were developed based on next-generation high-performing hardware and the Huawei Versatile Routing Platform (VRP). The Cloud Engine S5731-S supports simplified operations and maintenance (OM), intelligent stack (iStack), and flexible Ethernet networking. It also provides enhanced Layer 3 features and mature IPv6 features. The Cloud Engine S5731-S can be used in various scenarios. For example, it can be used as an access or aggregation switch on a campus network or as an access switch for Metropolitan Area Network.

Short-term operating temperature [C(F)] -5C to +50C (23F to 122F) at an altitude of 0-1800 m (0-5906 ft.) Restriction on the operating temperature variation rate [C(F)] When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1C (1.8F) every time the altitude increases by 220 m (722 ft.). The device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met: The operating temperature can exceed 45C (113F) for a maximum of 96 consecutive hours in a year. The total time when the operating temperature exceeds 45C (113F) in a year is less than or equal to 360 hours. The number of times the operating temperature exceeds 45C (113F) is less than or equal to 15 in one year. If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur. Devices cannot start when the temperature is lower than 0C (32F). The maximum transmission distance of an optical module used for short-term operation cannot exceed 10 km.
