Hi @angeloPV9 they will operate fine. While the MR52 APs will want to see and negotiate 30W PoE+ power upon bootup, they will never draw more than 21 watts maximum, and in all likelihood they will average between 6 to 12 watts, but keep an eye on it to confirm.
Go to the Switch > Switches page and click into the switch and click on the power tab. You will see a "Consumption" section and a "Budgeted" section. The number to worry about is the consumption. The budgeted number is just reflecting the total amount of theoretical power that could be consumed, as if every device pulled the full 15 or 30 watts of power it advertised via CDP/LLDP when it first negotiated.
See attached screen shot. I have a compact MS220-8P switch running 7 PoE devices all the time (MV cameras and MR APs). Looks at my "Budgeted" section, it says 140W/124W. That's showing that the switch max budget is 124W of PoE power, and those 7 devices (at max power draw) would take 140W. That's because 2 of my devices are an MV72 and an MR52 both of which negotiated 30W, and the other 5 devices negotiated 16W, so there's the 140W number. It rounds 15.4W to 16W when doing this to err on the conservative side.
But notice the consumption tends to hover around 41 to 45 watts. Will that fluctuate? Sure. I don't watch it that closely, but I've never seen it over 60 watts, not even halfway to the max the switch can deliver.
Hope that helps!
MR52 has the following power requirements:
(802.3at required; functionality-restricted 802.3af mode supported)
MS128-8FP is showing the following for PoE/PoE+ capabilities
MS120-8 FP includes 124W PoE/PoE+
Up to 30W per port
Not sure how it can do 30W per port for all of them, since 124W / 8 = 15.5W
Or am i misunderstanding something?
@ww wrote:The ms can go up to 30w per port.
So to me this means, that each port can individually in theory go up to 30W, but just not all at the same time 😃
