About the 470-AATP
The Dell 470-AATP is a Dell Networking Cable QSFP+ to QSFP+ 40GbE Passive Direct Attach Copper 3m engineered for high-speed interconnectivity over a 3.0-meter span at 40GbE. Utilizing precision twinaxial copper conductors terminated with fixed connectors, the 470-AATP provides low-latency physical transport while consuming less than 0.1W of power. In Dell's infrastructure catalog, 470-AATP connects PowerEdge servers to top-of-rack switches and storage arrays.
Compatibility
The 470-AATP cable is compatible with Dell PowerEdge servers and PowerSwitch systems including R730, R740, S4148F-ON, S5248F-ON. The 470-AATP connects directly into matching 40GbE ports without intermediate transceivers. Operating over 3.0 meters, the 470-AATP complies with standard SFF specifications and requires appropriate Forward Error Correction settings on host interfaces.
How to identify a genuine unit
Genuine Dell 470-AATP cable assemblies feature a white printed flag label displaying DP/N 0J9G5Y, cable length 3.0M, and Dell Networking branding. Connected switch operating systems such as Dell OS10 read the internal 470-AATP EEPROM, verifying authentic Dell serialization and cable telemetry.
Buying used
When evaluating a used 470-AATP cable, inspect the twinaxial outer jacketing for severe kinks, crushed shielding, or conductor strain near the molded connector hoods. Test both metal connector shells on the 470-AATP to ensure that pull-release latches engage firmly into host cages. Verify that connected 470-AATP ports establish a stable physical link without packet errors.
