About the T340

The Dell PowerEdge T340 is an enterprise tower server engineered for computing and virtualization workloads. Powered by 1 Intel Xeon E-2100 and E-2200 Series, Core i3, or Pentium Processors (up to 8 cores, 95W TDP) across 4 memory slots supporting up to 64GB DDR4-2666 ECC UDIMM, the T340 balances throughput and memory capacity. In Dell's server catalog, the T340 succeeded the POWEREDGE-T330 and was followed by the POWEREDGE-T350, positioned alongside rival systems including PROLIANT-ML30-GEN10, THINKSYSTEM-ST250.

Options and compatibility

Processor support on the T340 utilizes 1 LGA1151 sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the T340 require DDR4-2666 ECC UDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. The T340 tower chassis accepts X7K8W (3.5-inch LFF) drive carriers depending on backplane selection. Networking on the T340 uses Network Daughter Card (NDC), and expansion cards install into Up to 4 PCIe Gen3 slots risers.

How to identify it

Physical identification of the T340 is verified by the 14th-generation silver-gray brushed aluminum honeycomb bezel with the T340 badge on the front chassis ear. The pull-out information tag on the T340 control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9, the server identifies as T340 with active firmware, slot mapping, and power telemetry.

Buying used

When evaluating a pre-owned T340, inspect the LGA1151 CPU socket pins for damage and ensure retention clips are intact. Run Dell ePSA diagnostics across all 4 memory slots of the T340 to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the T340 match in wattage and that iDRAC9 Enterprise remote console is enabled. Ensure required T340 drive caddies and bracket accessories are present.

Works together

Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).

12Gb SAS uses Mini-SAS HD (SFF-8644) connectors; older 6Gb gear uses Mini-SAS (SFF-8088). Adapter cables exist, but the link runs at the slower speed.
