48 hospitality APs on one 740W Switch

For an upcoming deployment, I am looking at a situation where 47 hospitality APs (505H) will be connected to a single PoE Switch (740W PoE, Aruba 6200).

Using power measurements, I maxed out at around 9 Watts PoE usage of one AP, and the math gives me 15.5W/Port of available power.

 

Is there anyone with a similar setup willing to share some experiences?

Hi, 

 

you can check the data sheet to know the "worst case" PoE consumption to dimension the switch

 

Also take into account if the same switch has to feed VoIP phones... Every device counts...

Unless you're planning on using the USB port or POE PSE capability of the AP-505H (on more than a few of them), you'll be fine with the power budget that's available.

But be aware that the AP-505H will try to reserve the full 25.5W 802.3at POE budget (via LLDP) unless you disable USB & PSE using the ap-poe-power-optimization provisioning parameter (which drops the requested budget to 14W).
