I have several FS-726's without problems. My small port count boxes are Amazon's finest (BV-Tech) and I see there's a 24+4 port POE unmanaged Gig switch rated at 390 watts. I may buy one for my next project.

Pretty much, I split switches for AP's and Phones to separate boxes. Now, a power cycle will reboot all the AP's and not affect the phones. In hospitality, I have never had more than 3 phones and the Raspberry Pi at one time, so that's on a 9 or 10 port POE box and the AP's are on a 10.
