<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
