Never mind, I already figured out a usage. If one of the machines
connected to an outlet gets stuck and you want to cycle the power on
that outlet (probably the main reason to use RPC's in the first place)
you want to bring down the other systems on that outlet down cleanly.
Shutting down the whole UPS/RPC system is currently the only option
and this could be made more fine grained.
Best regards, Arjen
