Graviton SAS cable for Dell PowerEdge R440 FRN2J

Internal SAS cable for Dell PowerEdge R440

This black internal cable connects the hard-drive backplane to the PERC controller in a Dell PowerEdge R440 server. It carries SAS signals between the drive cage and the RAID card so the operating system sees every installed drive. The part number FRN2J identifies the exact fit for this chassis. System builders and IT technicians use it when they replace a damaged harness or add a second backplane.

Tested for continuous SAS throughput

Each unit is 100% tested before delivery to confirm signal integrity across the full length. The wiring maintains stable SAS communication under sustained drive activity such as rebuilds, backups or database workloads. No intermittent disconnects appear during extended read and write cycles. The cable is certified to CE standards for electromagnetic compatibility in rack environments.

Black moulded connectors lock into place

The black moulded ends seat firmly into the backplane and PERC headers without play. Latching tabs prevent accidental unplugging when drives are hot-swapped or the chassis is slid on rails. Routing follows the factory channel so airflow to the drives and controller is not blocked. Installers do not need special tools — the connectors click in and stay seated. Buyers who need a different length or a Y-splitter for dual controllers cannot use this single-run harness.
