R730XD thinks it is a R730
I have an R730XD that we purchased new. After some recent firmware, the system motherboard suddenly thinks it is a R730. There has been no hardware changes, no motherboard changes, etc.
Everything still works except when we boot, we receive the following error...
CBL0001: Backplane 0 power cable disconnected.
Now..when I press F1 the system continues to boot and it is booting off the two drives in the rear flex bay. All of the drives are powered up and the PERC sees all of them. The backplane does have power, it just seems we are getting this error because the motherboard thinks it is a R730 instead of an XD.
I have checked and reseated all the cables. I borrowed a rear flex bay board from another system and swapped them but that didn't make any difference. The only difference I can see with this R730XD and the other three is that when I boot, the system says 'PowerEdge R730' instead of 'PowerEdge R730XD'.
I downloaded the Platform Update ISO and ran through it fully. No luck.
I did a full reset on the iDRAC also.
Any thoughts on what to try or how to force the motherboard to realize it is an R730XD again?
Thanks.

Hello thanks for choosing Dell and welcome to our community.
Could you check the right ear control cable? The location can be found here.

have you checked the BIOS version in the system which are fine and effected one, check all the possible firmware please share your input to understand if the issue is still open or closed.

Sorry for the delay in replying. I reseated the right ear control cable but…no difference.
Thanks.

@Praveen.Singh
The working systems I have are currently on older firmware. I have not tried to backrev it that far yet. I did try to backrev it a few versions but…not as far as the working systems.

Hello, you can check the version as Praveen mentioned and for the worst case senario, I would also not rule out the possiblity of replacing the right ear cable. I'd recommend to raise an official case https://dell.to/3ym537G

@DELL-Young E
I will try backreving the firmware down to the same as my working R730XD’s. Unfortunately, the support has expired for these so I don’t think I can open a case.
Are you suggesting replacing just the right ear cable or the entire right ear?
Thank you.

Hi,
Start of by checking the right ear cable. If it is inserted properly, best to re-attaching after removing it (AKA reseat). If you have a spare R730XDs, you can try the right ear components to identify which is faulty.

I did check the firmware. I downgraded the firmware on this unit to the same as one of my working R730XD's but...the system is acting exactly the same.
I have reseated the right ear cable...multiple times now. If I borrow a right ear from one of my working R730XD's...I am a little worried it might end up doing something that would leave me with two broken R730XD's. Have to debate how to handle that. Is the XD data stored on the chip with the USB and VGA ports?

One thing I have noticed. My working R730XD shows a Backplane 1 Firmware version 3.31. My broken one shows a Backplane 1 firmware version 1.09. I have been trying to figure out where to obtain that firmware from. I have matched the BIO's and PERC firmware between them at this point. The working unit under Enclosure shows drives 0 - 13 (correct). The broken one shows drives 0-17 with 14-17 being Slot Empty (true...those slots don't exist). I can't seem to find firmware 3.31 for that Backplane anywhere.
Thanks.

I found an copy of backplane 3.03 in an old download directory and applied it. No change, but the backplane is updated a bit now.
Thanks.

Hi,
Point taken, we might not know what it can lead to. If you're getting replacement part, I suggest both the ear and cable. I do not know the architecture of the server's hardware, but there were troubleshooting done before on the same issue you're having. The ear connection is the root cause.
