CBL001 Signal cable turn on issue.
Hello,
I have a Dell PowerEdge R730XD with the 12x 3.5inch Backplane option. The system boots fine when the CBL001 cable is not connected but does not turn on when the cable is connected. Have tried using other cables but to no use. Would anyone know what the possible cause might be?

Hello,
please can you tell me which is the cable you talking about? It is the cable from the backplane?
And what is the error when the server doesn't post?
Thanks

@DELL-Marco B Hi Please see the attached pictures. The error comes when the cable is not connected but when it is connected then the server does not turn on.

It is normal that error comes when cable is disconnected.
We need to troubleshoot the backplane as it seems that issue.
What is mean it doesn't turn on? Any light or sounds? Fans are spinning?.
Do you have a backup of data? If so, can you try to remove all hard drives and check if it is the same?
Thanks

Hi Marco,
Can hear fans spinning, but system does not turn on when power button is pressed. Power button light does not come on. Do not have any data to backup. On the front panel the Health indicator LED is solid amber and Electrical Indicator LED is blinking amber.

Hello,
If it is the cable then you can find the part number on the label on the cable to try a different one.
If that doesn't help and we see it does not complete POST, I would recommend bring it down to minimum to post components:
Minimum to post (this is minimum components to POST, it won't boot, this is to test POST. If successful POST, put things back a little at a time until find faulting component)
The minimum components to allow the PowerEdge R730xd to complete POST are:
● System board
● One power supply unit
● One processor (CPU) in socket CPU1
● One memory module (DIMM) installed in socket A1
● Left control panel (for power button functionality)
● One backplane card
Remove anything not on that list: DVD, Hard drives, PERC controller, backplane, network card, NIC cable, any pcie cards, keyboard, mouse, USB devices, …. anything not on the list remove.
Leave the fans installed.
If it does not post then the issue is with one of those minimum to post components.
If you get successful POST, put things back a little at a time until you find the faulting component.
