Keep critical servers connected with a compact Gigabit Ethernet adapter designed for dependable wired performance. The AddOn 430-4156-AO pairs an Intel 82574 chipset with a PCI Express 2.0 x4 host interface to support 10/100/1000 Mbps networking through a single RJ-45 port. That combination makes it a practical fit for infrastructure teams that need consistent throughput, broad compatibility, and a straightforward upgrade path. This adapter is built for server environments where network stability matters more than feature bloat. Its plug-in card form factor helps it fit cleanly into standard PCIe expansion slots, while the single-port design keeps deployment simple for dedicated uplinks, management interfaces, or general-purpose server connectivity. For organizations replacing OEM network cards, the Dell 430-4156 comparable design offers a cost-conscious path without sacrificing the core hardware characteristics that matter in production. With lifetime limited warranty coverage and a proven Intel controller, this adapter is suited to long service cycles and controlled infrastructure refreshes. It is a focused, enterprise-ready NIC for teams that value predictable behavior, easy installation, and the right level of performance for mainstream server networking.
