SOPHOS APX 120 red light - no light

Hi there,

we have here two Sophos APX 120.

- One of them, shows a permanent RED light
- The another of them, shows permanent NO light

What you thinking about that? We was already trying to flash the APX's to recover them, but that was not working. They are connected to a sophos poe switch.

We tried already to use the "Sophos Flashing Tool" on the followed site, but it was not working. Maybe because we use an USB-C => RJ45 Adapter, and not a direct RJ45 port. But normally this should not be a problem, because it will be showed same as a NIC like a default RJ45 Port?

Sophos Access Point: Recover bricked access points using the Sophos Flashing Tool

Thanks.

Best Regards,
