Good day! New access point R720 untied. It does not load, the PWR LED is permanently lit in red.
Thanks to everyone, I tried different power supplies, it did not work, I took another AP R720 from the supplier, it booted without any problems with both the 802.3 af injector and PoH (95w). Damaged AP gave a refund. Our expert Maxim Malugin wrote that, most likely, this is a secure boot error.
