Does anyone have a bunch of 8851s deployed? Can I trouble you for a “show inline power” output? I’m looking for what normal operating power draw is for this model. No side cars, no USB, sort of thing.
I’ve got an 8865 showing 12.9W, and I’m hoping it’s less. We’re looking at selecting 8841 or 8851 and power draw is a concern. Startup too, but apparently, startup will cycle through.
