SMUGDESK Dual Mini SAS HD SFF-8643 Backplane Cable 1N2WK K43RY Dell PowerEdge R630

SKU CH-7QWE-S5GV2

Dual Mini SAS HD SFF-8643 cable connects RAID controller to backplane in PowerEdge R630 servers

  • OEM replacement for Dell PowerEdge R630 part numbers 1N2WK and K43RY
  • Dual Mini SAS HD SFF-8643 connectors link RAID controller to hard drive backplane
  • Multi-layer shielding resists electromagnetic interference for 24/7 data center operation
  • Precision-molded connectors with locking clips prevent vibration-induced loose contacts
  • Original routing length enables plug-and-play installation without chassis modification

Target Server and Role

This cable is a direct OEM replacement for Dell PowerEdge R630 servers, matching part numbers 1N2WK and K43RY. It connects the RAID controller to the hard drive backplane to maintain normal read and write performance for SAS and SATA drive arrays. It is built for 24/7 operation in data center environments.

Verify Controller and Backplane Ports

Before ordering, confirm your server uses Mini SAS HD SFF-8643 ports on both the RAID controller and the storage backplane. The cable provides two SFF-8643 connectors with locking clips for a secure fit. Ensure the existing routing path matches the original factory wiring for plug-and-play installation.

Sustained Signal Integrity

Multi-layer shielding isolates the signal from power supplies and cooling fans to prevent electromagnetic interference during continuous heavy loads. This design maintains stable high-speed transmission, reducing storage errors and abnormal disk recognition. Locking buckles keep connectors firmly seated despite long-term rack vibration.

Questions about this item

Does the package include any mounting hardware or do I need to source screws and clips separately?

The cable ships with precision-moulded SFF-8643 connectors that have integrated locking clips, so no extra mounting hardware is required for installation in the Dell PowerEdge R630.

How do I decide between the two part numbers 1N2WK and K43RY when ordering?

Both numbers refer to the same OEM replacement cable; either one will match the original wiring for the Dell PowerEdge R630 backplane connection.

What does the 8643 interface actually deliver when the cable is fitted inside a running server?

The dual SFF-8643 connectors provide high-speed SAS and SATA signal paths between the RAID controller and backplane, with multi-layer shielding that maintains stable transmission under continuous 24/7 data-centre loads.
