No, R500 is not supported on ZD1000. For supported AP models, refer the below release notes.
However, you can flash your R500 with Unleashed 220.127.116.11.127 firmware and it will work as a controller+AP.
You can download the firmware image from the below link.
Hi, thanks for your answer, can you please advised me what to do, I have 9 access points and one faulty ZD. Shell I get new zone director(if yes please tell me which one is compatible except 1200) or shell I flash them all with unleashed firmware? Which one is easiest and chipper solution?
@stoy_dimovski ZD1200 is the only controller which is not EOL so I don't think you have any other options.
If you want, you check for old ZD1100s as well but you can easily manage up to 25 APs using Unleashed.
One AP will become master, rest will be member and this all will work in HA mode, where available member AP will take over the master role, if there is any failure with master AP.
