About the 540-BCMU
The Dell 540-BCMU is a Dell Emulex LPe35002 Dual Port 32Gb Fibre Channel PCIe Adapter delivering 32Gb FC SAN connectivity across 2x 32Gb FC SFP+ over PCIe 4.0 x8. Powered by Broadcom ASIC architecture on the 540-BCMU, it offloads Fibre Channel protocol processing and provides high IOPS for storage fabric communications. In Dell's server portfolio, 540-BCMU connects PowerEdge hosts to high-speed enterprise storage arrays.
Compatibility
Compatible with PCIe slots across Dell PowerEdge servers including R750, R650, R760, R660, the 540-BCMU connects to enterprise Fibre Channel SAN fabrics from Brocade and Cisco MDS. The 540-BCMU auto-negotiates to supported fabric speeds and supports multipath I/O across redundant fabric paths within enterprise storage topologies.
How to identify a genuine unit
Genuine Dell 540-BCMU HBAs display a serialized label showing DP/N 0W34NY, Broadcom model codes, and factory World Wide Port Name (WWPN) identifiers. In iDRAC under Host Bus Adapters, the 540-BCMU card reports certified Dell firmware, hardware revision, and port status.
Buying used
When purchasing a used 540-BCMU, inspect the PCIe edge connector and onboard heatsink mounting pins for physical stability. Verify that matching optical transceivers are included with the 540-BCMU and clean. Confirm in UEFI Device Configuration that both 540-BCMU ports report factory WWPNs and negotiate speed properly.
