If the cabinet temperature is too high, the TRX starts overtemperature protection. Thus, the ongoing services are disrupted.
How to check the temperature threshold: Run the LST BTSEXD command on the MML client and set the parameters as required（IDTYPE=BYID, BTSID=BTS Index）.
Y => The cabinet temperature is higher than the temperature upper threshold. Go to procedure 2.
N => The cabinet temperature is normal. Contact Huawei Customer Service Center.
If the air conditioner or fan is faulty, rectify the fault. Wait until the cabinet temperature is normal, and then check whether the alarm is cleared.
Y => The alarm is cleared. No further action is required.
N => The alarm is not cleared. Go to procedure 3.
Check whether the preset threshold is too low. The normal cabinet temperature ranges from 0 to 40 degrees Celsius.
Y => The preset threshold is too low. Modify the threshold.
Log in to the LMT. Right-click the target site, and then choose Site Operation > Configure Site Attributes. Click Extended Attributes in the displayed Configure Site Attributes dialog box. Then, modify the temperature upper threshold. After the modification is complete, check whether the alarm is cleared. If the alarm is cleared, no further action is required. If the alarm is not cleared, go to procedure [4].
N => The preset threshold is in the normal range. Go to procedure 4.
Check the state of the temperature sensor. Replace the temperature sensor if it is faulty. Then, check whether the alarm is cleared.
