After Upgrade AP86xx series PDUs we lost the metering functionality

[STB]

Hello,

we upgraded our 50 PDUs from Type AP8653 to version 6.9.6 because of the Ripple20 security issue, using the recommended package provided by SE for that. After the upgrade we lost on several PDUs the connection to the metering board.

Before the Upgrade the Metering Board was seen in the GUI, later it isn't presented. I attached two pictures showing this.

In all our PDUs terminators are installed, so the recommendation to install a terminator isn't helpful, also changing the NMCs in the PDUs is no option at a 7x24x365 datacenter infrastructure.

Seems to be a problem of the firmware set provided in the actual package.

Thanks for helping hints on that issue

Kind regards

Stefan
