R740xd 24NVME failing
Hi all,
We are trying to convert a R740xd 24SFF to 24xNVMe. We have installed M7X6F - Dell PowerEdge R740xd 24x2.5 NVMe Backplane and added two 1YGFW Dell PowerEdge R-Series SSD NVME PCIe Extender Expansion Cards with PCIe cables (XW06Y + G5KWM) but it isn't booting.
System updated with last BIOS and iDRAC but when initializing all components flashes this red screen.

If we disconnect PCIe cables from the PCIe Extenders server boots normaly. What would be the issue?
Thanks in advance.

When I unplug the cables I see the same errors than shown in this thread.

Maybe is a problem with risers. My riser configuration is this:
Riser 1- GHGTP
Riser 2- J7W3K
I have PCIe extender cards in slots 1 and 4.

Maybe I need secondary riser RN1V2? I don't understand whats the problem if the installed risers have x16 PCIe slots.
What is the diference between 2A and 2D riser?

Hi,
Replacing the hardware with a completely new configuration might be a tough one to achieve to my opinion. We might not be able to help much as there is no documentation on all R740XD hardware configurations. So I'm going to base on the user guide to try to provide assistance.
Based on the user guide here, have you obtained all cables there is shown? I assume it is Figure 15 that you're trying to achieve. https://dell.to/3wJ9edh. The description says the cards are installed on Riser 1 Slot 3 and Riser 2 Slot 4.
The installation guide: https://dell.to/3wDxaPj it showed configuration 1A+2D+3A, which GHGTP is not 1A, it is 1D and J7W3K is not 2D, it is 2A.
Perhaps, I suggest contacting the Dell Sales department to confirm with the sales engineer which riser is needed for your NVMe configuration.
Just in case,
MDDTD is Riser 1A
RN1V2 is Riser 2D

I'm going to guess you are missing the red power cables and perhaps the green cables. As Joey said, there isnt much documentation on which parts/cables one would need to convert a system. Youu wont need the gray cables as I blv those are for the sas/sata controller. #Iwork4Dell

Finally the problem was with the 1YGFW cards. The correct cards for this config are YN9K8.

Hi Jtejada.ralco,
Any idea why it was that card? I am doing literally the same exact thing with the same exact issues (red screen pic you sent) all the things. I ordered 2 YN9K8. I just cant for the life of me tell the difference between a YN9K8 and other NVME extenders like 1YGFW and so on.
