Your SR650 V3 front bays are dark because the backplane cable kit is missing or shot. This is the exact SAS/SATA cable set for the 8x3.5-inch chassis front backplane. Drop it in, seat the connectors, and your drives light up in the BIOS. No guessing which part number fits — this one is built for that specific SR650 V3 bay layout. One kit, all the connections you need to get those bays talking to the controller again
