Dell PowerEdge R730/R740XD PCIe x16 Server Riser 2 Card Dell P/N: 0N11WF Tested

Dell PowerEdge R730/R740XD PCIe x16 Server Riser 2 Card 0N11WF

This part — Dell P/N 0N11WF — is a PCIe Riser 2 expansion card used in Dell PowerEdge R730 and R730XD servers (and also applicable in R740XD in similar riser positions/configurations). It provides additional PCI‑Express expansion capability inside the server.

📌 What It Is

Type: PCIe riser card

Part Number: 0N11WF

Servers Supported: Dell PowerEdge R730 / R730XD (and similar models like R740XD with matching riser architecture)

Function: Adds an internal PCIe x16 slot for installing expansion cards (NICs, HBAs, RAID, GPUs, etc.)

Riser Location: Riser 2 bay inside the chassis

Slot Provided: One or more PCIe expansion slots (full‑height/full‑length, typically x16 based on chassis config) — actual lane width depends on configuration.

This part lets your server support additional adapter cards without using the onboard slots directly on the motherboard. It essentially extends a PCIe connection through a daughter board inside the server.

🔧 How It Works in the Server

Dell’s design for R730/R730XD includes multiple risers:

Riser 1: Usually supports x8 or multiple low‑profile cards

Riser 2 (this one): Typically provides a full‑height, x16 PCIe slot for larger cards

Riser 3: Another set of slots for further expansion (often full‑height)

Installing the 0N11WF riser in the Riser 2 bay gives you a vertical PCIe slot (x16 electrical/physical) to add expansion cards such as 10GbE NICs, Fibre Channel HBAs, RAID controllers, GPUs, etc.

According to the official Dell documentation for the R730:

Slot 4 on Riser 2 is a full‑height, full‑length PCIe slot with x16 link width for expansion cards.

🧩 Typical Uses

This riser card is used when you want more expansion capability than what is available on the onboard connectors. Typical cards installed via this riser include:

10 GbE (SFP+ or RJ45) NICs

25 GbE or faster network adapters

RAID/SAS controllers

Fibre Channel HBAs

GPU or accelerator cards (in servers that support it)

🛠 Installation Notes

The riser inserts into the server’s midplane and provides vertical PCIe slots for added cards.

You’ll need appropriate retention brackets and clearance inside the chassis for full‑height cards.

Some configurations in the R730 may require both CPUs installed to use all riser slots.

The actual number of PCIe lanes available at that slot can vary based on riser configuration and processor setup.

🧠 Summary

Dell P/N 0N11WF is a PCIe x16 server riser card (Riser 2) for PowerEdge R730 / R730XD (and compatible with R740XD) that provides an internal expansion slot for full‑height, high‑bandwidth PCIe cards like NICs, HBAs, RAID controllers, and more
