<div>That's not to say that the Phone might be sending a malformed request. I'm sure the first thing the Juniper TAC is going to have me do is a packet capture.</div><div><br></div><div>Fun times, wohoo.</div><div>

we've connected it to one of our Juniper switches that provide
802.3at power.
<div><br>
</div>
<div>However the backpack (or the camera) does not appear to
work with it. (Works fine with the power cube)</div>
<div><br>
</div>
<div>Is there anything we have to do to enable PoE Plus
(802.3at)? I know the switch is providing it. (Its
registering it as a class 4 device, but the phone is only
drawing 7.4W, out of a Max of 30W)</div>
