Product overview

The HPE Ethernet 10Gb 2-port 560FLR-SFP+ Adapter is a dual-port network adapter in the 10 Gigabit Ethernet FlexibleLOM category. It is identified as a plug-in card and is designed around two networking ports. The product data provided describes it as an Ethernet 10Gb 2-port 560FLR-SFP+ Adapter, but does not list additional performance figures, bus details, or interface specifications beyond the category and port count. For procurement teams, this makes the core identification straightforward: HPE branding, the 662243-B21 identifier, and a two-port 10GbE FlexibleLOM positioning. Because only limited specification data is available, configuration validation should focus on matching the adapter name, category, and port count to the intended server or network deployment.
