Internal power cable for Dell PowerEdge R720 R820

This internal power cable connects a 16-bay 2.5-inch hard-drive expansion cage to Dell PowerEdge R720 and R820 servers. It carries the power rails required by the cage so all installed drives receive stable supply. The part matches Dell references N2R9K and CN-0N2R9K. It is intended for administrators expanding internal storage capacity on these platforms.

Verify cage and backplane compatibility before

Confirm the server chassis houses an 8-bay 2.5-inch cage that supports expansion to 16 drives and that the backplane provides the matching power connector. Ensure the cable routing path inside the chassis is clear and that the power distribution board has a free header of the correct pin-out. This cable does not adapt to other drive form factors or server models.
