Intel PWLA8492MT PRO/1000 MT Dual Port Server Adapter

The Intel PWLA8492MT PRO/1000 MT Dual Port Server Adapter is a PCI-X dual-port Gigabit Ethernet NIC designed for cost-effective 10/100/1000Base-T migration in server environments. The dual-port design delivers two independent RJ-45 Gigabit connections over standard Cat-5 cabling from a single PCI-X expansion slot — an operational and density advantage in servers with limited expansion bays. PCI-X at 64-bit width and 133MHz frequency provides a theoretical bus bandwidth of approximately 1GB/s per direction, more than sufficient to sustain both ports at simultaneous 1Gbps full-duplex without bus saturation. Intel SingleDriver technology simplifies multi-card fleet management by consolidating driver packages across the PRO/1000 family, reducing the image management complexity that varied NIC inventories historically imposed.

This adapter belongs in the hands of a system administrator maintaining a legacy PCI-X server infrastructure — rack servers from the early-to-mid 2000s running Xeon Nocona, Irwindale, or Dempsey-generation processors. The PRO/1000 MT was Intel's enterprise Gigabit standard for that era and remains well-supported under the OS versions those servers typically run. For any deployment targeting current-generation PCIe servers, this card is architecturally incompatible and should not be purchased. For its intended environment — PCI-X slot expansion, 1Gbps infrastructure, link aggregation or failover via Intel ANS — the PRO/1000 MT Dual Port remains a proven, stable component with a long field history. The included low-profile bracket provides 1U rack deployment flexibility alongside the standard full-height configuration.
