Extensive driver support helps ensure trouble-free installation in a broad range of systems. Timesaving pre-OS, after-hours, and remote capabilities-including 3Com Managed PC Boot Agent-reduce the need for site visits and minimize work disruptions. These NICs are fully standards-compliant, delivering world-renowned 3Com reliability backed by a globally supported Limited Lifetime warranty. Their broad compatibility with hardware and software-today and in the future-helps preserve your Gigabit Ethernet investment.

• Autonegotiation transparently configures NIC to match hub- or switch-port connection speed-10, 100, or 1000 Mbps
• TCP, UDP, and IP checksum offloads reduce CPU workloads for enhanced system response and network scalability
• Deep packet buffering, Jumbo Frames, interrupt coalescing, and flow control accelerate data transfer and reduce retransmissions
• Traffic prioritization and efficient multicast control give right of way to time-sensitive applications such as VoIP and multimedia
• 3Com Managed PC Boot Agent and other remote management features help lower network TCO
• IEEE 802.3 support helps ensure seamless integration with standards-compliant hardware, software, and management platforms
