Enterprise Network Adapter

The Dell QLogic QL41262HLCU-DE is a dual-port SFP28 PCIe network adapter built for Dell PowerEdge servers and compatible workstations. It provides 10/25GbE connectivity for data centre, virtualisation and high-performance computing workloads. The part number 415DX identifies this as a genuine Dell replacement component. OEM design ensures direct integration with supported Dell systems.

Sustained Load Behaviour

Advanced offload capabilities reduce CPU overhead during continuous high-throughput traffic. The PCIe Gen3 x8 interface maintains bandwidth for extended Ethernet, FCoE and iSCSI sessions without bottlenecks. Dual-port architecture balances load across links for consistent performance in virtualised environments. Low-profile and full-height brackets support reliable airflow in dense chassis configurations.

10/25GbE Dual-Port SFP28

The single specification that decides fit is the dual-port 10/25GbE SFP28 interface on a PCIe Gen3 x8 slot. Buyers needing a different port count, speed grade or connector type cannot use this adapter. Compatibility is limited to Dell servers and workstations with available PCIe slots matching the x8 electrical requirement.

Questions about this item

How much heat does the QL41262HLCU-DE generate under continuous 25GbE load?

The QL41262HLCU-DE is a passive PCIe adapter with no onboard fan, so thermal output depends on chassis airflow and SFP28 module choice; Dell validates it for standard server operating temperatures.

Which SFP28 transceivers and cables must I already own to use the dual 10/25GbE ports?

You need two SFP28 modules or direct-attach cables rated for 10GbE or 25GbE Ethernet, plus a Dell PowerEdge or workstation with a free PCIe Gen3 x8 slot and the appropriate low-profile or full-height bracket.

Will the 415DX adapter negotiate 10GbE links with my older SFP+ switches and NICs?

Yes, the QL41262HLCU-DE supports 10GbE and 25GbE rates, so it will auto-negotiate down to 10GbE when paired with compatible SFP+ optics or DACs on legacy equipment.
