What is the operating temperature range of the CE series switches

The CE series switches can operate normally within an ambient temperature range of 0°C to 40°C (altitude: 0 m to 1800 m).
Description:
- When the altitude is between 1800 m and 4000 m, the highest operating temperature for the CE12800 series switches reduces by 1°C every time the altitude increases by 220 m.
- When the altitude is between 1800 m and 5000 m, the highest operating temperature for the CE8800&CE7800&CE6800&CE5800 series switches reduces by 1°C every time the altitude increases by 220 m.
- The preceding temperature values refer to the ambient temperature, whereas the temperature shown in the display command output is the PCB surface temperature near high-power chips in the chassis. Whether the temperature is normal depends on whether it is within the temperature alarm threshold. Therefore, if the displayed temperature of a switch does not exceed the alarm threshold, the switch is operating under a normal temperature and has no risk of overtemperature.
