Hello,

I read these errors in the log

How can I solve it ?

Hi, the built-in SSD flash is broken. If you have a service, you can RMA it. Otherwise, you'll have to open the device, replace the SSD (it's a 2.5-inch drive), and then reinstall NOS.

BR.

Thanks for the reply.

Is it enough to replace the SSD flash and install the firmware with USB?

What version of NOS should I install and where can I download it?

Hello,

I replaced the compact flash

I can't find the firmware (any version), is there anyone who could provide it to me?

Thanks in advance
