Hi Thimozabi

So the SYS LED also can not trun on? Only power LED? 

Maybe you can use the console cable to have a try, I mean use the Putty.

Hi Panda.

No the SYS LED and whole initialization process does not start. So yes, only PWR LED goes on, (even though i have waited 1 day and several hours)

The console cable does not respond to either USB and RJ-45, i think its perhaps because the initialization is not done?

I have a TS2500G-10MPS POE switch wich is working without question, and i can access it without any problems via the GUI (havnt tried Console)

Maybe you can try to upgrade the frimware and you can refer to the FAQ.

hello, were you able to access the switch? I have the same problem, the pwr light is on, the sys light does not come up and I cannot access the siwtch through the console port after having done the reset

It seems the device is faulty, you may check the warranty for RMA.

@Thimozabi 

Hello I have exactly the same problem as you. But would it be possible to recover an image on another swicth of this model and to redo the installation via tftp if so which could put me a uImage.img in download at the end to perform the test and can be saved to other users if it was functional thanks Gerard.

Hello, i think i had similar issue with the old TL-SG3424.

I described my progress here:

https://forum.hddguru.com/viewtopic.php?f=13&t=41367

I still need a working config (default factory config, or anything) mainly for reference, but it might resurrect my unit, as the fw updates didn't and the config is definitely corrupt/empty.

I also started a topic on this forum about the same issue a few days ago. (the search function of this forum is very poor, it brings up quadzillions of posts for like 'configuration file', most of which have perfectly no relation to the search term, so i gave up searching the forum, it is not for humans i think.

Thanks for the answer I think recompile the gpl code to see if it can work again.
