HPE NC523SFP 10GbE dual-port adapter

This HPE 593717-B21 NC523SFP is a refurbished 10Gigabit Ethernet server adapter that uses a QLogic cLOM8214 network processor. It delivers 10,000 Mbps per port across two SFP+ slots for an aggregate 40 Gbps full-duplex throughput. The card plugs into an 8-lane PCI Express x8 slot and is compatible with x4 and x8 bus widths. Typical power draw is 17W.

Suits servers needing two 10G SFP+ links

This adapter fits administrators adding dual-port 10GBase-X connectivity to HPE or standards-compliant servers with an available PCIe x8 slot. It is not for systems that lack a PCIe x8 or x4 slot or that require a different physical interface. Buyers needing more than two ports or a fibre type not supported by SFP+ transceivers should consider other options.

PCIe x8 host interface with dual SFP+ cages

The single specification that determines fit is the PCI Express x8 host interface combined with two SFP+ expansion slots. The card occupies a plug-in card form factor measuring 7.6 by 11.1 by 1.3 inches and weighs approximately 1.28 oz. It carries RoHS environmental certification and operates at a typical 17W.

Questions about this item

Does my server need a PCI Express x8 slot to install this 10GbE card?

The card uses a PCI Express x8 host interface and is compatible with x4 and x8 bus widths, so an available x8 or x4 slot is required.

Will the SFP+ ports on this NC523SFP card work with my existing 1Gb SFP modules?

The card provides dual SFP+ ports running at 10,000 Mbps per port with 10GBase-X technology; compatibility with 1Gb modules depends on the module and switch configuration.

What indicator confirms the card is operating at the full 40 Gbps aggregate throughput after installation?

The card delivers 40 Gbps aggregate full duplex across its two ports; verifying link speed and duplex settings in the OS or switch shows it is running as intended.
