Slight noob question (still trying to figure out all these server connectors).
When purchasing my bare bones HL15 I selected the
SFF 8673 -> 4x 7-Pin SATA adapters. I was getting everything ready to put into the motherboard and noticed the SATA side of the connector has this extra 8 pin connector labeled P4. What is this used for?
When googling SFF-8643 to 4x sata adapters most of them don’t have this extra 8 pin connector.
