Cisco 3900 Series Integrated Services Routers (ISR) are designed to power the next phase of branch-office evolution, providing rich media collaboration and virtualization to the branch while reducing operating costs.

Services On-Demand: The Cisco 3900 Series Integrated Services Routers reduce initial capital outlays by decoupling the delivery of software from hardware on optional service modules. In addition, you receive a Universal IOS image capable of enabling all of Cisco’s rich IOS features and allowing you to quickly deploy new services.

Investment Protection: The Cisco 3900 Series reduces deployment costs and increases flexibility. The platform offers a modular, field upgradable motherboard called the Services Performance Engine (SPE). SPEs allow you to invest in a 3900 Series ISR today and boost its performance later by upgrading to a higher-performance engine. Investment protection is also offered with support for a majority of existing modules from previous-generation ISRs.

Energy Efficiency: The Cisco 3900 architecture includes higher-efficiency power supplies with intelligent power management, with full Cisco EnergyWise feature support in the future. Both ISR 3925 & 3945 routers support dual power supplies for power supply redundancy for branch or retail environments running missios-critical applications

High Performance: The Cisco 3900 Series offers significant performance improvements over previous-generation ISRs.
