Dell Server R440 BP1 SAS A0 cable is not connected or is improperly connected
Hello, im trying to setup a Dell R440 4LFF Server, the BP is directly connected to the Mainboard using a Supermicro SAS-Kabel OCuLink - Mini-SAS HD cable.
Once i start the system i get this error message:

Ive triede updating the BIOS Idrac basically everything but the problem still persists.
Even using a PERC H330 Controller and directly connecting it wont work for me.
Does anyone know a fix for this?
Heres Pictures of the Cabel Routing in the server:

Hello,
I can't help with the Supermicro cable but this should be the cable you need:
To connect backplane with H330 you will need this cable

SAS cable, from PERC adapter to X4 BP, for X4 HDD config, R440
