AXC F 2152 doesn't boot correctly

Hello forum,

I have a AXC F 2152 PLC that 2 days ago presented with all of its LEDs off except for the UL indicator on the power connector. There was no power outage reported. I couldn’t connect to it with PLCnext Engineer and wasn’t able to access the webserver (error 502: Bad Gateway), however, I was able to access the internal file system using WinSCP and copy the Output.log file:

I performed a firmware update via ssh but there was no change, afterwards I attempted a reset type 2 but the LEDs didn’t turn on in orange color as expected (see image and video attached):

Vid_IMG.zip (2.5 MB)

after the LEDs turned off again I tried to access its internal files with WinSCP as “admin“ and the printed password in the PLC but was denied access because the password was incorrect even though I didn’t change it.

My suspicion is that this issue could be related to the internal microSD in the PLC, I will try to access it with a linux PC but I would like to hear any input or process that could help me restore the controller.

Thanks in advance.

Hello, this is the information displayed by gparted. The first partition shows a warning as shown in the image.

I also performed a check on all partitions and got this file as a result, there were no abnormalities according to gparted but after plugging it back to the PLC, the behavior remained the same.
