illegal class reported by PD

hi

I've connected some (17) Ubiquiti WAPs to an ICX7150-ZP48.

some WAPs arent loading (all connected with direct patch cables in the lab).

it seems to be randomly not always the same WAP.

"sh inline power" output shows this error"

illegal class reported by PD

all WAP are the same model (ubiquitin AC-Lite) and have the same firmware.

it doesn't seem that the switch has any power capacity issues.

I've tried different POE configurations:

"inline power power-limit 8000" (up to 20000)

"inline power power-by-clas 3" (and 4)

and just "inline power"

the switch version is SPS08095d and the POE firmware is 02.1.8 Build 004.

any idea what happing here?

thanks

One comment, Ubiquiti had two revisions of the AC-LITE. The original version was not 802.11af/at compatible but rather ubiquiti-24v only. Is it possible you have a mix of older and newer APs?

In ubiquiti's page you can see the following:

*** UAP-AC-LITEs with a date code prior of 1634 or board revision before 33 only support 24V passive PoE.

maybe its that?
