This Dual Mini SAS HD SFF-8643 backplane cable is a dedicated replacement storage signal cable for Dell PowerEdge R630 servers, corresponding part numbers 1N2WK and K43RY. It establishes stable data communication between the server RAID controller and hard drive backplane to ensure normal read and write performance of your SAS and SATA hard disk array.

Produced according to enterprise server hardware specifications, this internal cable adopts multi-layer shielding structure to effectively isolate electromagnetic interference from power supplies, cooling fans and other internal components. Continuous high-speed signal transmission is guaranteed under heavy load, preventing storage errors, abnormal disk recognition and data transmission failures.

All SFF-8643 connectors use precision injection molding with standard pin arrangement. Built-in locking buckle ensures firm insertion, effectively preventing intermittent connection problems caused by long-term rack vibration. The cable layout and length are consistent with the original factory wiring, which can be directly installed without cutting or modification to the chassis.

This replacement cable is the ideal spare part for IT maintenance work, data center server overhaul, storage expansion project and replacement of aging, broken original cables. Widely applied in enterprise server rooms, monitoring storage systems and industrial computing equipment.

Important Reminder: This cable is specially built for Dell PowerEdge R630. Please confirm your server model and original part number 1N2WK / K43RY before ordering. It cannot be universally used for other server models with different internal layout.
