What Is the Operating Temperature Range of the CloudEngine Series Switches?

What Is the Operating Temperature Range of the CloudEngine Series Switches?

The CloudEngine series switches can operate normally within an ambient temperature range of 0°C to 40°C (altitude: 0 m to 1800 m).

  • When the altitude is between 1800 m and 4000 m, the highest operating temperature for the CloudEngine 12800 and 12800E 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 CloudEngine 8800, 7800, 6800, and 5800 series switches and CloudEngine 16800 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.
