What is the operating temperature of boards and what are the upper and lower temperature thresholds
You can use the display temperature command to view the current card temperature and temperature alarm thresholds. In the command output, the Temperature.(C) field shows the current card temperature, the Upper field shows the upper temperature alarm threshold , and the Lower field shows the lower temperature alarm threshold. In a poorly ventilated environment, temperature alarms may be generated frequently because the card temperature is high and the upper temperature alarm threshold is small. To avoid this problem, clean the air filter of the device or increase the upper temperature alarm threshold. NOTE: The temperature thresholds are preset and you do not need to change them. If you have special requirements on the temperature, contact Huawei engineers.

What is the operating temperature range of AR routers

The operating temperature range of the AR120&AR150&AR160&AR200&AR1200&AR2200&AR3200&AR3600 series routers is 0°C to 45°C.

The display temperature all command displays the highest temperature in an AR router but not the actual ambient temperature.

If no alarm is generated, the router is working normally and the temperature is within the allowed range.

NOTE:

You can use the display temperature all command to check the temperature alarm thresholds and current temperature of all boards on a router.
