Specifications

About the 540-BBOZ

The Dell 540-BBOZ is a Dell Intel X550 Dual Port 10GBASE-T RJ45 PCIe Adapter engineered to deliver 10GbE network transmission across 2x 10GBASE-T RJ45 over PCIe 3.0 x4. Powered by Intel controller architecture on the 540-BBOZ, it executes hardware-level protocol processing, RoCE, and SR-IOV virtualization while maintaining a thermal envelope of approximately 13W. In Dell's networking portfolio, 540-BBOZ 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-BBOZ mounts directly into FHHL / LPHL PCIe Adapter locations. The 540-BBOZ installs into a standard PCIe 3.0 x4 expansion riser slot with matching bracket profile. Cabling the 540-BBOZ 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-BBOZ include VMware ESXi, Red Hat Enterprise Linux, and Windows Server with native Dell drivers.

How to identify a genuine unit

Authentic Dell 540-BBOZ units carry an identification label displaying DP/N 0540-BBOZ and Intel model code 07161T along with Dell regulatory marks. In iDRAC Network Devices inventory, the card registers under part number 540-BBOZ with active link state, port MAC addresses, negotiated speed, and certified Dell firmware. Onboard physical indicators on the 540-BBOZ provide link status and port activity monitoring.

Buying used

When purchasing a pre-owned 540-BBOZ, examine the gold edge connector fingers for scratches, peeling contacts, or missing surface-mount capacitors. Ensure that the 540-BBOZ PCIe mounting bracket (low-profile or full-height) is intact and properly aligned for chassis installation. Validate in iDRAC Lifecycle Controller that the 540-BBOZ is recognized with certified Dell firmware and passes diagnostics under sustained 10GbE network traffic.
