Applicable Versions:
All versions
Applicable Models :
All models
Fault Symptoms:
When certain UPS models (e.g., CyberPower 1500 CP1500PFCLCD) are connected to the TOS system, the TOS system may fail to recognize the UPS or may disconnect the UPS after establishing a connection.
Cause of Failure:
The hardware configurations of UPS units vary across different brands and models, leading to inconsistent polling intervals. Consequently, this variability affects the TOS system's ability to reliably identify and maintain a stable connection with the UPS.
