Dell X710 + i350 network adapter, MPN 555-BCKO-RFB, combines two network controllers on one quad-port card for server environments that need both high-speed links and 1Gb connections.
The X710 side provides two 10Gb SFP+ ports, while the i350 side provides two 1Gb Ethernet ports. This mix supports connecting faster network links alongside equipment or network segments using 1Gb Ethernet, with the different speeds available on one adapter.
This particular listing identifies the card as refurbished. It is intended for server use where a combination of 10Gb SFP+ and 1Gb Ethernet connectivity is useful.
