Product Description
The IBM 19K4309 is a Fast Ethernet Network Interface Card (NIC) that provides standard 10/100 Mbps network connectivity. Featuring a single RJ45 port, this card is designed to offer reliable Ethernet communication for servers and workstations that do not require the higher bandwidth of Gigabit Ethernet. It is suitable for a wide range of applications, including general office networking, internet access, and connecting to older network infrastructure. This NIC utilizes a PCI Express (PCIe) interface, which is a modern standard offering better performance and scalability compared to older bus architectures like PCI or PCI-X. The card supports both 10 Mbps (Ethernet) and 100 Mbps (Fast Ethernet) speeds, automatically negotiating the best available speed with the connected network device. It also supports full-duplex operation, allowing for simultaneous data transmission and reception, which can significantly improve network throughput in busy environments. Designed for integration into IBM systems, the 19K4309 is typically easy to install and configure. It may come with support for low-profile brackets, making it compatible with smaller form factor chassis. While Fast Ethernet is considered legacy for high-performance servers, it remains a functional and cost-effective solution for basic networking needs or for systems that are not network-intensive. This card serves as a dependable option for ensuring network connectivity in compatible IBM hardware.
