About the 540-BBRM
The Dell 540-BBRM is a Dell Intel X710 Dual Port 10GbE SFP+ OCP 3.0 Adapter engineered to deliver 10GbE network transmission across 2x 10GbE SFP+ over PCIe 3.0 x8 OCP 3.0 SFF. Powered by Intel controller architecture on the 540-BBRM, it executes hardware-level protocol processing, RoCE, and SR-IOV virtualization while maintaining a thermal envelope of approximately 8W. In Dell's networking portfolio, 540-BBRM 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-BBRM mounts directly into OCP 3.0 Small Form Factor locations. The 540-BBRM slides into the rear OCP 3.0 mezzanine bay with an ejection latch, preserving PCIe riser slots. Cabling the 540-BBRM 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-BBRM include VMware ESXi, Red Hat Enterprise Linux, and Windows Server with native Dell drivers.
How to identify a genuine unit
Authentic Dell 540-BBRM units carry an identification label displaying DP/N 0K93PG and Intel model code K93PG along with Dell regulatory marks. In iDRAC Network Devices inventory, the card registers under part number 540-BBRM with active link state, port MAC addresses, negotiated speed, and certified Dell firmware. Onboard physical indicators on the 540-BBRM provide link status and port activity monitoring.
Buying used
When purchasing a pre-owned 540-BBRM, examine the gold edge connector fingers for scratches, peeling contacts, or missing surface-mount capacitors. Ensure that the 540-BBRM OCP pull-latch mechanism is intact and properly aligned for chassis installation. Validate in iDRAC Lifecycle Controller that the 540-BBRM is recognized with certified Dell firmware and passes diagnostics under sustained 10GbE network traffic.

Works together
How the Dell 540-BBRM 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.

FAQ
What is the advantage of OCP 3.0 over standard PCIe cards?
OCP 3.0 cards install into a dedicated chassis slot without consuming a PCIe riser slot, and can be serviced from the rear without opening the chassis cover.
Does this card support Dell iDRAC Network Controller Sideband Interface (NC-SI)?
Yes, it supports NC-SI, allowing iDRAC management traffic to be shared across the production 10GbE ports.
