About the R240
The Dell PowerEdge R240 is an enterprise 1U rack 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 R240 balances throughput and memory capacity. In Dell's server catalog, the R240 succeeded the POWEREDGE-R230 and was followed by the POWEREDGE-R250, positioned alongside rival systems including PROLIANT-DL20-GEN10.
Options and compatibility
Processor support on the R240 utilizes 1 LGA1151 sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the R240 require DDR4-2666 ECC UDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. The R240 chassis utilizes X7K8W (3.5-inch LFF) drive trays across its 3.5-inch storage bays. Networking on the R240 uses Network Daughter Card (NDC), and expansion cards install into Up to 2 PCIe Gen3 slots risers.
How to identify it
Physical identification of the R240 is verified by the 14th-generation silver-gray brushed aluminum honeycomb bezel with the R240 badge on the front chassis ear. The pull-out information tag on the R240 control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9, the server identifies as R240 with active firmware, slot mapping, and power telemetry.
Buying used
When evaluating a pre-owned R240, 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 R240 to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the R240 match in wattage and that iDRAC9 Enterprise remote console is enabled. Ensure required R240 drive caddies and bracket accessories are present.

Works together
How the Dell PowerEdge R240 connects to servers, storage and the network: 4 ways, with the parts and products on each path.
Fibre Channel SAN
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).

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.

Direct-attached SAS
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.
