Cisco Integrated Service Routers Generation 2 (ISR G2)
Cisco 3900, 2900, and 1900 Series Integrated Services Routers (ISR) 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 experiences with video, 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 application 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.
As part of the available security services, Cisco Firepower Threat Defense for ISR provides the industry-leading threat protection for the entire network surface areas as part of the Cisco Intelligent WAN (IWAN) deployment for hybrid WANs and direct Internet access. With Cisco Firepower services, the ability to detect anomalies, enforce policy, and accelerate mitigation is now built into the ISRs. By using existing ISR G2 and the Cisco 4000 Integrated Services Router, customers gain continuous visibility and control to defeat malware across the extended network and the full attack continuum: before, during, and after an attack.
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 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.
You can order the platforms as base 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.
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, 3925E, 3945, and 3925 routers, which differ primarily in performance capabilities and service-module slot count.
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 you can upgrade with higher-performance engines that will be developed in the future. The Cisco 3945E ships with the Cisco Services Performance Engine (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. Table 1 lists the part numbers for the Cisco 3900 Series platforms and SPEs.
