Product Name
D33025 (PWLA8492MTBLK5)Intel PRO/1000 MT Dual-Port Gigabit Ethernet Server Adapter
Model Interpretation:
- “D33025”: Intel’s internal PCB part number for the adapter’s core circuit board, referenced in component sourcing and repair contexts .
- “PWLA8492MTBLK5″: Formal product model—”PRO/1000” indicates Intel’s gigabit Ethernet series, “MT” denotes multi-port technology, and “BLK5” specifies the bundled bracket kit .
- “Dual-Port”: Confirms two independent RJ-45 interfaces for simultaneous network connections .
2. Product Description
The D33025 (PWLA8492MTBLK5) is an enterprise-grade dual-port gigabit Ethernet adapter engineered by Intel for high-bandwidth, low-latency data transmission in servers, workstations, and ruggedized industrial systems across data centers, manufacturing automation, and mission-critical computing environments . As a plug-in network interface card (NIC), its core functions include:
- Enabling 10/100/1000 Mbps auto-negotiable connectivity via two RJ-45 ports, supporting seamless integration with legacy and modern Ethernet networks .
- Offloading TCP segmentation and large send operations to the onboard Intel 82546 controller, reducing CPU utilization by up to 30% in high-throughput scenarios .
- Supporting remote management protocols (WFM, RIS, SNMP/DMI) for centralized monitoring and configuration of server network interfaces .
Key technical strengths:
- Dual-Port Redundancy: Two independent gigabit ports enable link aggregation or failover, ensuring 99.999% network uptime for critical applications .
- Versatile Compatibility: Supports 32/64-bit PCI-X 1.0 and PCI 2.2 buses, working with both legacy and modern server motherboards (e.g., Supermicro X7DAL-E) .
- Rugged Deployment Flexibility: Includes full-height and low-profile brackets for installation in standard or space-constrained server chassis, ideal for ruggedized workstations .
- Advanced Diagnostics: Built-in cable testing and interrupt moderation features simplify troubleshooting and optimize network performance .
