Server Adapter for 10 Gbit/s Fibre

The HPE NC523SFP is a dual-port 10GBase-X network card that plugs into a PCI Express 2.0 x8 slot. It uses SFP+ cages so you can choose the transceiver and cable type that match the link. The low-profile plug-in card fits standard server chassis and carries RoHS certification.

Suited for Dual 10 Gbit/s Links

This adapter serves administrators who need two independent 10 Gbit/s fibre connections from a single x8 slot. It does not satisfy buyers who require more than two ports, higher signalling rates, or a different bus interface such as OCP or USB.

Deciding Specification: PCI Express 2.0 x8 Bus

The card occupies a PCI Express 2.0 x8 slot and presents two SFP+ ports for 10GBase-X operation. Verify that the host system provides an x8 electrical connection and that the chosen transceivers match the intended fibre type and distance.

Questions about this item

Will the PCI Express 2.0 x8 interface of the NC523SFP work in my server's older PCIe 1.0 slots?

The card uses a PCI Express 2.0 x8 host interface and is backward compatible with PCIe 1.0 slots, though it will operate at the lower 1.0 speeds.

How can I verify the NC523SFP is functioning correctly after installation?

Check the server BIOS or OS device manager to confirm the card is detected as a 10GBase-X adapter on a PCI Express 2.0 x8 link, then verify link lights on the SFP+ ports when cables are connected.

Does the NC523SFP include SFP+ transceivers or cables, or must I purchase them separately?

The adapter provides two SFP+ ports for 10GBase-X connectivity; SFP+ transceivers and fiber or direct-attach cables are not included and must be sourced separately.
