That is exactly what I will eventually try (assuming I ever get any time
to work on my test cluster some more).
It is clear that, no matter what I do, I cannot prepare for

Do you know that on APC PDUs, you can group outlets across several

The plugin is configured to talk to just one outlet on one of the PDUs and the
