Intel EXPI9402PTBLK-1PK Dual Port Gigabit Network Card

Dual-Port Gigabit Server Adapter

The Intel EXPI9402PTBLK-1PK adds two RJ45 ports over a PCI Express x16 lane, delivering 10/100/1000Mbps connectivity for servers or workstations that need redundant or aggregated links. It targets administrators upgrading older rack systems or expanding I/O capacity on boards with spare full-height slots. The full-height bracket and Category 5 twisted-pair support suit legacy copper infrastructures. It is not for builders needing fibre uplinks or 10 Gigabit throughput.

PCI Express x16 Installation Requirements

The card occupies a full-height PCI Express x16 slot and measures 0.85" in height by 5.10" in width, so the chassis must accept a standard full-height bracket and provide enough clearance for the dual RJ45 connectors. Each port negotiates 10/100/1000Base-T speeds independently, freeing the system from shared-bus contention common on older architectures. Driver support covers Windows 2000, Windows Server 2003, Red Hat Linux 2.4x and FreeBSD 4.x. It is not for low-profile enclosures or boards lacking a physical x16 slot.

Sustained Multi-CPU Load Balancing

Dedicated PCI Express bandwidth per port eliminates bus sharing, allowing each gigabit link to maintain line-rate throughput during prolonged transfers. The adapter balances network interrupts across multiple processors, reducing CPU bottlenecks in multi-socket servers under continuous traffic. Category 5 cabling limits the maximum segment length to the standard for that media. It is not for environments where jumbo-frame offload or hardware acceleration beyond the listed operating systems is required.
