Hello all, I have a D15 camera not working

I tryed to reset following istructions at this post

> [@How do I reset my MOBOTIX product to the factory default settings?](https://community.mobotix.com/t/how-do-i-reset-my-mobotix-product-to-the-factory-default-settings/233):
>
> Instructions on how to restore the factory default settings can be found in your product’s User Manual or Quick Installation Guide. You can download them from the [MOBOTIX web site.](https://www.mobotix.com/en/support/download-center/documentation/user-manuals). Reset camera to factory default from the web interface Step 1. Access the camera via browser. Step 2. Open the Admin Menu and scroll down to the Configuration section and click on Reset configuration to factory defaults Step 3. A new window will be open. From the drop-down menu select Completely replace…

but nothing helped

The issue started after a reboot (before this reboot the camera was working ok), after boot leds flash this way  
first leds 2 and 4 flash 7-8 times fast  
then leds 2 stay on not blinking, and leds 3 and 4 blinking fast forever  
leds 1 never turn on  
ethernet interface never turn on, on the switch where the camera is connected the “link” led never turn on

Does that sequence of blinking mean some error specific?

Thanks you  
Roberto

Hi @RobertoG,

I apologise for the delay in getting back to you.

If you can no longer access a camera, the only option is to restart the camera in the factory settings on the hardware side.

You can find the procedure for this here:  
3.2.4 Starting the Camera with Factory (Network) Settings

If there is still no link (no LED) on the switch that confirms the data transfer, there may be a defect in the camera.
