Foundry's award-winning FastIron Edge Switch (FES) now includes the X-series products to provide greater flexibility, higher reliability, enhanced security, extensive redundancy, and a new level of high performance by combining Gigabit over Copper (GoC) and 10 Gigabit Ethernet, while simplifying network management complexity and reducing on-going training expenses. The FES X-series increases a network's return on investment (ROI) and decreases total cost of ownership (TCO) by offering improved functionality through a common feature set controlled by industry-standard Command Line Interface (CLI) syntax, all in a compact (1.5 Rack Units) form factor at industry-leading prices. The FES X-series is an advanced hardware platform that provides advanced Layer 2 switching and is software upgradeable to deliver full enterprise Layer 3 routing. The FES X-series is the ideal networking platform to deliver 10GbE from the edge to the core.The Foundry Networks FES X-series establishes the next benchmark in delivering the most adaptable feature set, combined with high density GoC with 10 Gigabit Ethernet upgradeability in a compact form factor. Specifically, the FES X-series establishes the industry's leading price-performance value for fixed Ethernet solutions with the addition of removable and replaceable 10 Gigabit Ethernet modules in a 1.5 Rack Unit (RU) form factor. The FES X-series can be initially installed using four "Small Form Pluggable" (SFP) Gigabit Ethernet ports, and then later upgraded to support one or two "10 Gigabit Small Form Factor Pluggable"(XFP) modules.To meet existing and emerging network requirements, the FES X-series delivers a full complement of standards-based, feature rich switching and Base Layer 3 routing capabilities, hardware and software resilience, rich quality of service (QoS) controls including prioritization and rate limiting, standard and extended ACLs, integrated Gigabit over Copper (GoC) Ethernet ports, and more. The extensive feature set supports network requirements ranging from basic connectivity to multicast-based streaming audio/video applications for converged services including Voice over IP (VoIP), using a software upgrade to full enterprise Layer 3.
