AP7920 Switched Rack PDU:Near overload fake alarm

[Anonymous user]

Dears,

I am facing a problem with my AP7920 APC Switch Rack PDU where it is keeping on sending continuously Alarms:

Switched Rack PDU:Near overload which seems to be a fake Alarm (after turning off all the equipments connected to it, the alarm was still received).

Note : Another Alarm is also continuously received: Switched Rack PDU:Communications lost followed by Switched Rack PDU:Communications established.

Please advise about a solution for this issue.

Switched Rack PDU:Communications lost/established frequently usually means the device has an internal communication fault and it likely needs to be replaced. As the device gets older, it is more prone to problems like this because of the aging electrical components not being able to talk to each other. This is also likely related to the "fake" overload alarm because the device cannot tell what the current status is because it lost communication.

To be sure, can you provide event.txt, data.txt, and config.ini files from the PDU please (Instructions on doing that here -> How can I download Event, Data, Configuration, and Debug files from my Network Management Card? | FA...)? Do you know the serial number on the PDU?
