Come to think of it... we’d need to know if your 8851s are the pre-v8 hardware or v8 or above.

</div>
<div>V8 they went from class 3 to class 4. </div>

That would be great.
<div><br>
</div>
<div>We’re concerned with out of the box 8851s. No side cars. Maybe add a few watts for USB powering of devices. </div>
<div><br>
</div>
<div>We understand that they may request 30w on power up, then revert down to ~15w. Which means phones may not all come up at once if our power supplies are not sufficient. </div>
<div><br>
</div>
<div>But as long as there’s sufficient normal operating power, we should be good. </div>
<div><br>
</div>
<div>Complicating factor is we have APs to contend with as well. They’re sucking power, too!</div>
<div><br>
</div>
<div>Thanks again. </div>

<p>Sure, I can do that for you in the morning.</p>

</p>
<p>Check the datasheet on the KEM as well - those draw different power. The A-KEM is supported with 1 per, BEKEM with 2 (big easy is BE, code name for the model).</p>

</p>
<p>If you're running gear with a low budget, "show power inline <interface> detail" tells you what it's actually drawn, in case you need to dip into manual policing. The LLDP-MED/CDP power request values can be higher than what it really needs.<br>

<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.</p>
