Dell PowerEdge NVMe Signal Cable H4RH0

This blue PCIe signal cable connects the 24-bay 2.5 NVMe backplane to the PCIe subsystem inside Dell PowerEdge R840 and R940 servers. It is built for continuous datacentre operation and supports high-density enterprise storage arrays requiring reliable signal integrity under heavy workloads.

Verify server model and backplane configuration

Confirm the chassis is a PowerEdge R840 or R940 equipped with a 24-bay 2.5 NVMe backplane, as this cable is specific to that architecture. Check the existing cable routing paths and connector orientation to ensure the replacement matches the physical layout of your current installation.

OEM cable restores factory airflow

The Dell-manufactured assembly replaces a damaged or degraded link without introducing third-party variance in impedance or length. Its original routing design preserves intended airflow channels and maintains the PCIe signal quality required for stable NVMe array performance in 24/7 production environments.

Questions about this item

Does the H4RH0 cable ship alone or with any brackets or screws?

The listing covers the NVMe PCIe signal cable itself; mounting brackets and screws for the 24-bay 2.5 backplane are not included and must be sourced separately.

Which cable variant matches a PowerEdge R840 versus an R940?

Part number H4RH0 is specified for both the PowerEdge R840 and the PowerEdge R940, so a single version serves either server model.

What does the 24-bay rating mean for actual NVMe drive throughput?

The cable carries PCIe signals from a 24-bay 2.5 NVMe backplane to the subsystem, preserving signal integrity so each drive can operate at its rated PCIe speed.
