Dell PowerEdge C6520 Internal Data Cable

This genuine Dell cable carries the part number 1RP2W and is built for the PowerEdge C6520 server node. It connects the system motherboard to the hard drive backplane for SAS and SATA drives. The black connector type is R1B/LK 2.5N and the item is new. It serves as a direct replacement for a damaged or missing cable in that specific chassis.

Before ordering verify the server model

Confirm that the target system is a Dell PowerEdge C6520 before purchasing this part. Check that the existing cable uses the R1B/LK 2.5N connector style shown in the product images. Ensure the motherboard and backplane ports match this interface so the cable routes correctly inside the node. This part will not fit other Dell server models or different backplane configurations.

Sustained data transfer stability

The cable is engineered to OEM specifications to maintain signal integrity during continuous operation. It supports high-speed SAS and SATA traffic between the motherboard and storage backplane without signal degradation over time. The form-fitted design keeps routing consistent which helps prevent intermittent faults under prolonged load. This reliability is essential for enterprise environments running constant storage workloads.

Will this cable carry SAS and SATA traffic at full speed once installed in a C6520 node?

Yes, the 1RP2W cable is engineered to OEM specifications to maintain signal integrity for both SAS and SATA drives across the motherboard-to-backplane path in the PowerEdge C6520.
