C9200L-24P-4G-E Noise Problem

我们这一台交换机,当室外温度到达中午的时候,交换机就会进行高速运转。产生的噪声很大。请问这是怎么一回事。谢谢。

@lawson-luo hi, if device exposed to high temperature or in any fan failure, working fans may speedup to cater required cooling. for the 9200L series check below document for noise levels and temperature levels which are recommend.

从你的描述上来理解,似乎设备伴随温度的升高而导致设备的FAN转速加快,以加强对设备的散热。

那么需要考虑:1.按照设备的位置是否有空调,然设备保持在一个比较正常的室温;如果没有,可能是这方面的问题。2.关于C9200运行的温度,可以参考如下。

 temperature

Normal operating temperature* and altitudes:

●  -5°C to +45°C, up to 5000 feet (1500m)
(-5°C to +40°C for C9200CX-8UXG-2X and C9200CX-8UXG-2XH)
●  -5°C to +40°C, up to 10,000 feet (3000m)

*Minimum ambient temperature for cold start is 32°F (0°C)

Short-term* exceptional conditions: (9200L/9200 only)

●  -5°C to +50°C, up to 5000 feet (1500m)
●  -5°C to +45°C, up to 10,000 feet (3000m)
●  -5°C to +45°C, at sea level with single fan failure

*Not more than following in one-year period: 96 consecutive hours, or 360 hours total, or 15 occurrences

解决方案
1、改善散热环境:确保交换机周围通风良好,远离热源或杂物堆积,环境温度控制在10℃-40℃(理想工作温度范围) 。建议:"改善通风条件,避免阻挡散热"。
2、调整风扇模式:若交换机支持,将风扇模式从标准模式(全速)改为静音模式,可显著降低噪音(但需监控温度以防过热) 。
3、硬件维护:

清洁与更换风扇:定期清理积尘;若风扇异响,按原型号更换新风扇(注意接口线序匹配) 。
检查电容状态:若出现高频"吱吱声",需排查电源滤波电容或主板电容是否鼓包、漏液 。
4、设备升级:高温环境(如无空调机房)可选用工业级交换机,其智能风扇系统按温度调速,比商业级更静音 。避免使用廉价交换机,选择开关电源噪声控制较好的型号 。
