HP PCA FLEX IO NIC 1P 1GBE (L19378-001) is a Flex IO network interface card for adding a wired network connection through an HP LAN Flex port. Its designation identifies a single-port 1GbE adapter, giving a workstation a Gigabit Ethernet connection through the Flex IO interface.
The part is listed for HP Z2 SFF/Mini G4, Z2 Mini G4 and Z2 Tower G4 workstations. It is a targeted spare for systems using this Flex IO LAN arrangement, rather than a general-purpose network card for any computer. The model reference helps distinguish it from other Flex IO network options.
