Ewon Cosy 131 shows only PWR, not USR

Ewon Cosy 131 shows only PWR light, Level 1 and Level 2 resets don’t follow the LED patterns I am expecting (no flashing USR). Seems to periodically reboot, but I’m not sure.
Cant’s see it in a new download of eBuddy.
Can’t ping it on 10.0.0.53
It’s been configured previously and hasn’t been used since 2013/14

You can try the Recovery process:

But if that does not detect it, it’s probably defective and will need to be replaced.
