IBM 22P4909 2-Port 100Mb/s RJ-45 Fast Ethernet 100Base-TX Network Card

Product Description

The IBM 22P4909 is a dual-port Fast Ethernet network adapter designed to provide 100 Megabits per second (100Mbps) connectivity for each port. It utilizes standard RJ-45 connectors, allowing for easy connection to common Ethernet network infrastructure using Cat5 or higher-grade UTP cabling. The card interfaces with the host computer via a PCI (Peripheral Component Interconnect) bus, a widely adopted standard for expansion cards in computers from the mid-1990s through the early 2000s. With two independent 100Mbps ports, this network card is well-suited for servers or workstations that need to connect to multiple networks, provide network redundancy, or support specific network configurations like network bridging or teaming. The 100BASE-TX standard ensures a robust and reliable connection for typical business networking tasks, including file sharing, internet access, and application connectivity. To utilize the IBM 22P4909, a compatible PCI slot must be available in the host system, and the appropriate device drivers need to be installed for the operating system. While 100Mbps is slower than modern Gigabit Ethernet, this card remains valuable for maintaining or upgrading older systems, or for applications where 100Mbps is sufficient and cost-effective. It represents a reliable solution for adding dual Fast Ethernet capabilities to compatible IBM or other PC-compatible systems.
