You'll just need the cables Diego had mentioned. There isn't any cabling to go from controller to board, the communication would just run over the PCIe connector.
I am attempting to upgrade my R240 server from the on-board S140 software raid controller to a H330. The H330 is installed and working however when the server boots it throws an error: iDRAC Settings:CBL0009: Backplane 1 connector A0 is not connected. UEFI0116: One or more boot drivers have reported issue(s).Check the Driver Health Menu in Boot Manager for details. Continuing past this error everything works as normal, I can configure the controller, install an OS and boot to the OS. I know I can disable F1 on error in settings but I would rather this error be fixed rather than ignored. I purchased a generic SAS SFF-8643 to SFF-8643 cable to connect the H330 to the backplane, could this be the issue? Do I need a specific cable from Dell? Having the correct perfect length cable would also be a plus but I can not find any part numbers for this. The other thing I have come across on my troubleshooting and research is the existence of a "signal cable" from the H330 to the motherboard. I do not have one of these, and I also have no idea where this would connect to on the motherboard. A part number for this if it does indeed exist would also be useful. Thanks.
