What to do if a thermal alarm sounds on the Harmonic Spectrum X Server?
- DDr. Jordan Bates MDAug 3, 2025
If a thermal alarm sounds on the Harmonic Server, and the Operator Panel Module Fault displays amber, or the Fan Fail LED is lit on one or more PCMs, it indicates that the internal temperature exceeds a pre-set threshold. First, check that the local ambient environment temperature is within the specified limits. Then, inspect the installation for any airflow restrictions at the front or rear of the MediaStore, ensuring a minimum gap of 25 mm at the front and 50 mm at the rear. Also, check for dust build-up and clean as needed. Avoid excessive re-circulation of heated air from the rear to the front, and it is not recommended to use the MediaStore in a fully enclosed rack. If possible, shutdown the MediaStore and investigate the problem before continuing.
