Hello,

I’ve applied these patches to change the SATA port to PCIE

> **[GitHub - BenjKeiser/clearfog\_gt8k\_patches](https://github.com/BenjKeiser/clearfog_gt8k_patches/tree/main)**

> main

After having 2 of these cards connected, the device often becomes inaccessible over the network and the only way to reset is to remove power.

Sometimes it happens with a single card too, but not as often as with 2 cards. There is no log over UART.  
Those cards can draw up to 9W each (and require 3.3V 3A), is the board able to provide that much power to both of them? Or is there another issue here.

Only one one time there was something shown in UART when the device became inaccessible:

Any idea what the issue might be?
