Dell Server Motherboards

PowerEdge system boards for rack, tower and blade servers

About Server Motherboards

Dell calls the server motherboard a system board, and that is the term used throughout its documentation and on our listings. Searching for the Dell part number is far more reliable than searching by server model alone, because most PowerEdge models went through more than one board revision.

What is in stock

  • R-series rack servers - the largest group, spanning several PowerEdge generations
  • T-series tower servers
  • M-series blade servers
  • Earlier numeric-generation PowerEdge boards for legacy machines still in service

Board revisions are not always interchangeable

A single PowerEdge model can span more than one system board revision, and the revisions differ in ways that matter: supported processor family, memory type, and which onboard controllers are fitted. Two boards that both claim to be for the same server are not automatically equivalent. This is why the Dell part number from the existing board is the identifier worth having.

What a board swap involves

Replacing a PowerEdge system board is not purely mechanical. The service tag is stored on the board, so after a swap it has to be re-entered for the machine to identify itself correctly to Dell and to any support entitlement. iDRAC licensing is tied to the service tag, and iDRAC settings live on the board, so network configuration typically has to be redone.

The processor and memory usually transfer from the old board, but only if the replacement supports the same families - which is the revision question again.

Send us the service tag or the part number from the existing board and we will confirm the correct revision rather than matching on server model alone.

Frequently Asked Questions

Why does Dell call it a system board?

It is simply Dell terminology for the motherboard, used consistently across Dell documentation, service manuals and parts listings. Our listings follow the same convention, so searching for system board will find what other vendors label a motherboard.

Are all system boards for the same PowerEdge model the same?

No. Most PowerEdge models went through more than one board revision, and revisions can differ in supported processor family, memory type and which onboard controllers are fitted. The part number from the existing board is the reliable identifier; the server model alone is not.

What happens to the service tag when I replace the board?

The service tag is stored on the system board, so a replacement board arrives without your machine identity. It has to be re-entered after the swap, otherwise the server will not report itself correctly and support entitlement lookups will not match. iDRAC licensing is tied to the service tag as well.

Can I reuse my existing processor and memory?

Usually yes, provided the replacement board revision supports the same processor family and memory type. Where a model spanned a processor generation change, an apparently matching board may not run the CPU you already have. Confirm the revision before ordering.
