CISCO2911-V/K9全新思科路由器 Integrated Services Routers (ISRs) build on 25 years of innovation and product leadership. Cisco Integrated Services Routers Generation 2 (ISR G2) are architected to enable the next wave of branch-office evolution, enabling richer media CISCO2911-V/K9全新思科路由器experiences with video, CISCO2911-V/K9全新思科路由器and local compute resources for local application flexibility and survivability. Adding to the rich breadth of services available on the original ISRs - security, unified communications, wireless, and applicaCISCO2911-V/K9全新思科路由器tion optimization services - the ISR G2 routers enhance the reduction in overall branch-office expenses with the introduction of flexible services "on demand" through software licensing and simplified Cisco IOS® Software packaging.CISCO2911-V/K9全新思科路由器
The ISR G2 portfolio consists of three product families similar to the first generation of ISRs: the Cisco 3900, 2900, and 1900 Series Integrated Services Routers. From the Cisco 1921 CISCO2911-V/K9全新思科路由器through the Cisco 3945E, the portfolio provides increasing performance, module slot density, and features to match the needs of diverse branch offices running varying degrees of rich services.CISCO2911-V/K9全新思科路由器
You can order the platforms as base CISCO2911-V/K9全新思科路由器systems or bundled systems for security, unified communications, or application services. This ordering guide focuses on base system configurations and options, but most of the elements are applicable to bundle ordering as well. For a detailed list of advanced technology bundles on the Cisco ISR G2 routers, please refer to section 4 of this ordering guide. CISCO2911-V/K9全新思科路由器
1.1 Ordering the Cisco 3900 Series Integrated Services Routers
The Cisco 3900 Series Integrated Services Routers offer the highest performance and services density among the ISR portfolio. The series comprises the Cisco 3945E, Cisco 3925E, Cisco 3945, and Cisco 3925 routers, which differ primarily in performance capabilities and service-module slot count. CISCO2911-V/K9全新思科路由器
The Cisco 3900 Series ISRs offer a field-replaceable Cisco Services Performance Engine (SPE), which hosts the system route processor, enhanced high-speed WAN interface card (EHWIC) slots, and onboard Ethernet and digital-signal-processor (DSP) slots - an option available uniquely on the Cisco 3900 Series. The SPE is a modular motherboard that can be upgraded with higher-performance engines developed in the future. The Cisco 3945E ships with the Cisco SPE250, the Cisco 3925E ships with the SPE200, the Cisco 3945 ships with the SPE150, and the Cisco 3925 ships with the SPE100. When ordering SPE spares or upgrading, it is important to note that the SPE250 and SPE150 are supported only on Cisco 3945 platforms, whereas the SPE200 and SPE100 are supported on the Cisco 3925 platforms.
