An example of this is as follows:
All of these events happen without justification. The best way to guarantee that the events are false is to look at the log and you will see that several of the events (3 or more) will have the same time stamp. Additionally, these messages disappear upon removal of the card.
Assuming your Network Management Card firmware is up to date, the problem most likely lies with the Symmetra or Smart-UPS and its synchronization of the accessories, and is solved easily by updating the values in the two fields listed below. It is unlikely that the card itself is faulty, and thus replacing it will not solve the problem.
If the last "battery replacement date" field is not populated in the interface of the Web/SNMP Management Card (AP9606) or Network Management Card (AP9617/AP9618/AP9619), you may receive the erroneous messages. Quite often you will see the message Serial Communication Lost displayed (a lot of times from a Symmetra UPS). You can update this field with the following procedure:
Note: If this procedure is not applicable to your UPS or scenario, please review knowledge base FA156045 for additional information
