2-Port Server Adapter

The HPE NC523SFP 10Gb 2-port Server Adapter, part 593717-B21-HIGH-RFB, is a refurbished server network adapter for adding high-speed Ethernet connectivity. HPE identifies the base model as 593717-B21.

Its two SFP+ ports support 10 Gigabit Ethernet, and the card uses an eight-lane (x8) PCI Express interface. This provides a wired network connection for compatible server systems.

The connection setup depends on the network medium: copper uses a Direct Attach Cable, while fiber requires transceivers and fiber cables. HPE lists both full-height and low-profile brackets for the adapter, which can be fitted in standard or low-profile slots.
