Foundry Networks' second generation 10 Gigabit Ethernet modules are designed to deliver 20Gbps of wire-speed performance while doubling the density and optimizing serviceability. Foundry Networks offers industry's first two-port 10 Gigabit Ethernet card with next generation optics based on Xenpak transceivers. Xenpak transceivers offer hot-swappable (GBIC-Like) functionality for optimal serviceability, better sparing and network operations, reducing Total Cost of Ownership (TCO). Single-slot line card design is used for both 1-port and 2-port versions, for efficient, high-density 10GbE solutions. Install up to 28 10GbE modules in a single 15-slot chassis. Based on the industry's most flexible and cost-effective architecture, the 10 Gigabit Ethernet modules support all of Foundry's award-winning IronWare switching and routing capabilities. These include wire-speed, hardware based Layer 2 switching, IP and IPX-based Layer 3 routing, Access Control Lists (ACLs) and extended ACLs, traffic classification, prioritization, and marking, as well as support for jumbo frames.Use the standards-based 802.3ae 10Gigabit Ethernet modules in the NetIron, BigIron, and FastIron modular chassis products to meet the hyper-demands of today's Enterprise and Service Provider networking infrastructures.
