About the 540-BBGO
The Dell 540-BBGO is a Dell Broadcom 57416 Dual Port 10GBASE-T RJ45 PCIe Adapter engineered to deliver 10GbE network transmission across 2x 10GBASE-T RJ45 over PCIe 3.0 x8. Powered by Broadcom controller architecture on the 540-BBGO, it executes hardware-level protocol processing, RoCE, and SR-IOV virtualization while maintaining a thermal envelope of approximately 14W. In Dell's networking portfolio, 540-BBGO 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-BBGO mounts directly into FHHL / LPHL PCIe Adapter locations. The 540-BBGO installs into a standard PCIe 3.0 x8 expansion riser slot with matching bracket profile. Cabling the 540-BBGO 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-BBGO include VMware ESXi, Red Hat Enterprise Linux, and Windows Server with native Dell drivers.
How to identify a genuine unit
Authentic Dell 540-BBGO units carry an identification label displaying DP/N 03N6PY and Broadcom model code BCM57416-2T along with Dell regulatory marks. In iDRAC Network Devices inventory, the card registers under part number 540-BBGO with active link state, port MAC addresses, negotiated speed, and certified Dell firmware. Onboard physical indicators on the 540-BBGO provide link status and port activity monitoring.
Buying used
When purchasing a pre-owned 540-BBGO, examine the gold edge connector fingers for scratches, peeling contacts, or missing surface-mount capacitors. Ensure that the 540-BBGO PCIe mounting bracket (low-profile or full-height) is intact and properly aligned for chassis installation. Validate in iDRAC Lifecycle Controller that the 540-BBGO is recognized with certified Dell firmware and passes diagnostics under sustained 10GbE network traffic.

Works together
How the Dell 540-BBGO 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.
