I have a couple of IPE shelves in my CS1K that I no longer need wasting electricity (especially in the case of a power outage) so I have deleted all TNs, disabled the associated XPECs, removed the superloops from programming, and shut down the breakers in the base for 2 of the 3 shelves. Now the red light is on at the top of the pedestal and interloop tests keep running, so I've clearly missed something. Any idea what is left to do to decommission these for good?
