Huawei S6720S-S24S28X-A (24 Gigabit SFP, 28 Gigabit SFP +, AC power supply, front maintenance)
Huawei S6720S-S24S28X-A is a Standard 10 Gigabit Ethernet Switch with 24*Gigabit SFP ports, 28*10 Gigabit ports, built-in AC power supply (front) launched for the campus network market. The product supports a wide range of service features, comprehensive security control strategies, and rich QoS characteristics. The S6720S-S series adopt a front power supply design, with a total depth of only 220mm. This design allows for high-density gigabit/10-gigabit optical access interfaces to be widely deployed in aggregation or core layers of campus networks, as well as in small data center access scenarios, meeting the demand for full optical interconnection.The ports of this series of switches support flexible access for GE and 10GE, automatically recognizing the type of optical module installed, thus maximizing user investment protection and ensuring operational flexibility. In response to the high data traffic and non-blocking transmission requirements of data centers, the product can provide strong buffering capabilities and supports advanced buffer scheduling mechanisms, ensuring that the device’s buffering capabilities are utilized to the fullest.

| Operating ambient temperature variation limit [° C] | From 1800m to 5000m, the maximum temperature specification is reduced by 1 ° C for every 220m increase in altitude. The device supports short-term operation beyond the normal operating temperature range, provided that the following conditions are met: -Working temperature exceeds 45 degrees for a maximum of 96 consecutive hours in a year -The total time that the working temperature exceeds 45 degrees in a year is not more than 360 hours. -No more than 15 times in a year when the working temperature exceeds 45 degrees If one of the above three conditions is exceeded, it belongs to over-specification use, which may cause damage to the equipment or unknown situations. The device does not support starting at ambient temperatures below 0 ° C. The maximum distance at which the optical module is used for short-term operation shall not exceed 10 km. |
