Expand wired connectivity without consuming multiple slots. The StarTech ST4000SPEXI adds four Gigabit Ethernet ports through one PCI Express x4 interface, giving servers and workstations more network paths for segmentation, redundancy, and traffic isolation. At the core is the Intel I350-AM4 chipset, a proven choice for business-class network adapters where stability and consistent throughput matter more than consumer-grade extras. Support for PXE network boot simplifies bare-metal deployment, while Wake-on-LAN helps keep remote systems reachable when power management policies are in place. Auto MDIX and Auto Negotiation reduce setup friction, and 9K jumbo frame support helps move larger packets more efficiently in tuned environments. This card is a practical fit for infrastructure teams that need more than a basic single-port NIC. Four ports in one adapter can reduce cabling complexity, preserve expansion capacity, and support more deliberate network design across virtualization hosts, application servers, and high-availability desktops. With a 2-year limited warranty and RoHS compliance, it is built for deployments where reliability and lifecycle value matter.
