Dear Chanphirun! Please refer to the following suggestions: 1. The ambient temperature range of the product is as follows: -33°C to +55°C Check whether the temperature in the equipment room is normal, whether the air conditioner cools down properly, and whether the cabinet is ventilated properly. The board surface temperature may exceed 70°C when the ambient temperature is higher than 55°C. In such a case, wear protective gloves to handle the board. 2. An IDU 910A chassis supports air cooling, with air inlet on the left side and air outlet on the right side. If necessary, remove the side doors of the cabinet.
3. Check whether the fan module is faulty. If yes, replace the fan module. Check whether the heat dissipation hole on the IDU is covered or blocked. If yes, clear or remove the covering materials or obstacles.
4. Check whether the TEMP_OVER alarm is reported. If the ambient temperature is normal and no other heat dissipation problems exist, replace the board that reports the alarm. Thank you! |

You can compare the temperature on another device. If the temperature on the two devices is the same, it is normal. If the temperature is much higher, check the device according to the preceding suggestions. In addition, if the board slot is not checked, insert an empty board. |
