Extend network connectivity on PCI-based systems with a compact Gigabit Ethernet adapter designed for dependable wired access. The AddOn EXPI9301CT-AO provides a single open RJ-45 port with 10/100/1,000 Mbps support, making it a practical fit for environments that need to preserve existing hardware while restoring or upgrading network access. This adapter is a strong choice for IT teams maintaining older desktops, workstations, or servers that still have available PCI slots. It delivers the bandwidth needed for file transfers, application access, and routine LAN traffic without the cost and disruption of a full platform refresh. The open-port design keeps the installation simple and avoids unnecessary complexity in dense or budget-sensitive deployments. For organizations balancing uptime, compatibility, and procurement discipline, this card offers a clear path to extend the life of proven systems. It is especially useful when the goal is to add reliable wired networking to hardware that remains serviceable but lacks modern onboard Ethernet performance.
