Quad Port 10GbE Adapter for PowerEdge

The Dell Chelsio T540-BT adapter adds four 10GbE RJ45 ports to compatible PowerEdge servers. It is built for IT teams expanding network capacity in R640, R740, R740XD, R940 or R840 systems. The card uses a PCIe 3.0 x8 slot and the Chelsio Terminator 5 ASIC to handle TCP/IP, iSCSI and FCoE traffic. Virtualization clusters and storage networks benefit from SR-IOV support and hardware offload.

Sustained Load Behaviour

The Terminator 5 ASIC offloads protocol processing from the host CPU during continuous 10GbE streams. This keeps latency low and throughput steady across all four ports in 24/7 operation. Energy-efficient design limits heat output while maintaining line-rate performance for iSCSI and FCoE workloads. SR-IOV acceleration ensures consistent bandwidth allocation for multiple virtual machines sharing the adapter.

Pre-Installation Checklist

Verify the server is a supported PowerEdge model and has a free PCIe 3.0 x8 slot with the correct bracket height. Confirm Cat6a or Cat7 cabling is installed for runs up to 100 meters. Ensure the operating system and hypervisor include drivers for the Chelsio T540-BT controller. Buyers needing fibre connectivity or more than four ports should select a different adapter.

Questions about this item

How much power does the Chelsio T540-BT draw when all four 10GbE ports run continuously?

The adapter is designed for energy-efficient 24/7 operation in Dell PowerEdge servers, with the Terminator 5 ASIC optimising throughput per watt.

What slot and cabling must already be present in the server for this quad-port card to function?

A PCIe 3.0 x8 slot and Cat6a or Cat7 patch cables up to 100 metres are required for the four RJ45 ports.

Will the card fit and operate in a PowerEdge R740 that still uses older storage controllers?

Yes, it is validated for the R740 and other listed PowerEdge models, using a standard PCIe 3.0 x8 interface that coexists with existing controllers.
