IBM 44V5401 2793 MT-9402 I/O WAN PCI Network Adapter Card

Product Description

The IBM 44V5401 is a specialized network adapter card designed to provide Wide Area Network (WAN) connectivity for IBM systems. Identified by its 2793 MT-9402 model designation, this card interfaces with the system's motherboard via the Peripheral Component Interconnect (PCI) bus, a standard expansion slot interface prevalent in many server and workstation architectures of its era. Its primary function is to enable communication over long distances, connecting the host system to external networks, the internet, or other geographically separated locations. As a WAN adapter, the 44V5401 is typically equipped with specific ports and circuitry to handle protocols and physical connections associated with WAN technologies. This could include interfaces like serial ports (e.g., RS-232, RS-422) for modem or direct line connections, or potentially integrated CSU/DSU functionality for T1/E1 lines, depending on the exact variant and intended application. The card is crucial for establishing reliable data links required for branch office connectivity, remote access, or dedicated leased line communications. This adapter card is a key component for organizations that require robust and dedicated network connections beyond the scope of a local area network (LAN). Its integration into IBM systems underscores its role in enterprise networking solutions, providing the necessary hardware to bridge geographical divides and facilitate essential business communications over wide-reaching networks.
