The Brocade FastIron FGS648P Access Switch provides enterprise organizations with a flexible and feature-rich solution for building a secure and converged network edge. Upgradeable with 10-Gigabit Ethernet,PoE, and IronStack stacking technology, the FastIron GS Series gives enterprises the cost and operational benefits of a "pay-as-you- grow" architecture. It delivers the scalability, QoS assurance, resilience, and VoIP-readiness needed to implement a high-value converged solution that can scale to meet future growth at the network edge. An enterprise may initially deploy a standalone FastIron GS switch and later upgrade to IronStack stacking to scale the installation from one to eight stacked units to meet growing user requirements.
