AP1331 extension with AP1301 - Inactive status of new AP

Hello, I had an AP solutions based on 2 AP1331 connected to OS6360-10 and I would like to extend to Wifi coverage by adding 2 AP1301. When I connected them, after some time difficulties, they appeared in the AP module but in inactive status.
When they are plugged, when I’m connected to the SSID VVX-Salon, then I can’t go on the Web (meaning that i’m connect to them from my point of viex but internet isn’t “loaded” on.
I try to change PoE cable, without success. I try to restart them, without success.
Can someone guide me to investiguate where the pb could coming from ?
Tks a lot for your support.
