About the 540-BBGN
The Dell 540-BBGN is a Dell Broadcom 57412 Dual Port 10GbE SFP+ PCIe Adapter engineered to deliver 10GbE network transmission across 2x 10GbE SFP+ over PCIe 3.0 x8. Powered by Broadcom controller architecture on the 540-BBGN, it executes hardware-level protocol processing, RoCE, and SR-IOV virtualization while maintaining a thermal envelope of approximately 9W. In Dell's networking portfolio, 540-BBGN provides dedicated high-bandwidth fabric connectivity for clustered virtualization, network storage, and enterprise database hosts.
Compatibility
Engineered for Dell PowerEdge servers including R740, R640, R750, R650, the 540-BBGN mounts directly into FHHL / LPHL PCIe Adapter locations. The 540-BBGN installs into a standard PCIe 3.0 x8 expansion riser slot with matching bracket profile. Cabling the 540-BBGN requires 10GbE-rated media, including direct attach copper twinaxial assemblies, optical transceivers, or patch leads matched to its physical ports. Supported operating systems on the 540-BBGN include VMware ESXi, Red Hat Enterprise Linux, and Windows Server with native Dell drivers.
How to identify a genuine unit
Authentic Dell 540-BBGN units carry an identification label displaying DP/N 010DFV and Broadcom model code BCM57412-2P along with Dell regulatory marks. In iDRAC Network Devices inventory, the card registers under part number 540-BBGN with active link state, port MAC addresses, negotiated speed, and certified Dell firmware. Onboard physical indicators on the 540-BBGN provide link status and port activity monitoring.
Buying used
When purchasing a pre-owned 540-BBGN, examine the gold edge connector fingers for scratches, peeling contacts, or missing surface-mount capacitors. Ensure that the 540-BBGN PCIe mounting bracket (low-profile or full-height) is intact and properly aligned for chassis installation. Validate in iDRAC Lifecycle Controller that the 540-BBGN is recognized with certified Dell firmware and passes diagnostics under sustained 10GbE network traffic.

Works together
How the Dell 540-BBGN connects to servers, storage and the network: 3 ways, with the hardware on each path.
iSCSI and NVMe/TCP over Ethernet
Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.
