Hi @zafir ,
Welcome to the Xilinx Forums!
The use of an ATX power supply may be the cause of this issue. Using an ATX power supply can damage the card as discussed in AR 72298. This is also mentioned in the Getting Started guide UG1301 (v1.5 is applicable for the U280).
The red LED indicates that the card is experiencing a power delivery issue. I want to confirm, the card is visible in Vivado HW but the connection drops before you are able to load the golden image? Do you have a known working card that you can test in the same PCIe slot to ensure that there isn't a power related issue coming from the server?
We do recommend to always run the higher power cards with the PCIe AUX attached, so the card receives the power it is expecting.

Hi John, thanks for your answer. I have attached the screen short of errors which we face when we try to detect and flash via jtag. If some one has clue for these errors it will be helpful. Thanks.

Hi @zafir ,
I see that the first message wants to check that the target board is powered, given that you are seeing the red LED which indicates a power delivery issue on the card - I think this further points to the card having power related issues. As mentioned in the last post, the use of an ATX power supply may damage the card.
