Key Business Benefits of the Cisco 2900 Series Integrated Services Routers
Benefits |
Description |
Services Integration |
● The Cisco 2900 Series ISRs offer increased levels of services integration with voice, video, security, wireless, mobility, and data services, enabling greater efficiencies and cost savings.
|
Services On Demand |
● A single Cisco IOS® Software Universal image is installed on each ISR G2. The Universal image containsall of the Cisco IOS technology sets which can be activated with a software license. This allows your business to quickly deploy advanced features without downloading a new IOS image. Additionally, larger default memory is included to support the new capabilities.
● The Cisco Services Ready Engine (SRE) enables a new operational model which allows you to reduce capital expenditures (CapEx) and deploy a variety of application services as needed on a single integrated compute services module.
|
High Performance with Integrated Services |
● The Cisco 2900 Series enables deployment in high speed WAN environments with concurrent services enabled up to 75 Mbps.
● A MultigiGabit Fabric (MGF) enables high-bandwidth module-to-module communication without compromising routing performance.
|
Network Agility |
● Designed to address customer business requirements, the Cisco 2900 Series modular architecture offers increased capacity and performance as your network needs grow.
● Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.
|
Energy Efficiency |
● The Cisco 2900 Series architecture provides energy-saving features that include the following:
◦ The Cisco 2900 Series offers intelligent power management and allows the customer to control power to the modules based on the time of day. Cisco EnergyWise technology will be supported in the future.
◦ Services integration and modularity on a single platform performing multiple functions, optimizes raw materials consumption and energy usage.
◦ Platform flexibility and ongoing development of both hardware and software capabilities lead to a longer product lifecycle, lowering all aspects of the total cost of ownership, including materials and energy use.
◦ High efficiency power supplies are provided with each platform.
|
Investment Protection |
● The Cisco 2900 Series maximizes investment protection:
◦ Reuse of a broad array of existing modules supported on the original Integrated Services Routers provides a lower cost of ownership.
◦ A rich set of Cisco IOS Software features carried forward from the original Integrated Services Routers and delivered in a single universal image.
◦ Flexibility to adapt as your business needs evolve.

Benefits |
Modular Platform |
● The Cisco 2900 Series ISRs are highly modular platforms with several types of module slots to add connectivity and services for varied branch-office network requirements.
● The ISRs offer an industry-leading breadth of LAN and WAN connectivity options through modules to accommodate field upgrades for future technologies without requiring a platform replacement.
|
Processors |
● The Cisco 2900 Series are powered by high-performance multi-core processors that can support the growing demands of high-speed WAN connections to the branch-office while also running multiple concurrent services.
|
Embedded IP Security (IPSec) VPN Hardware Acceleration |
● Embedded hardware encryption acceleration is enhanced to provide higher scalability, which combined with an optional Cisco IOS Security license, enables WAN link security and VPN services (IPSec acceleration).
● The onboard encryption hardware replaces and outperforms the Advanced Integration Modules (AIMs) of previous generations.
|
Multigigabit Fabric (MGF) |
● The Cisco 2900 Series introduces an innovative Multi Gigabit Fabric (MGF) that allows for efficient module-to-module communication, enabling tighter services interactions across modules while reducing the overhead on the route processor.
|
TDM Interconnectivity Fabric |
● Unified communications services in the branch office are significantly enhanced with the use of a TDM interconnectivity fabric in the system architecture, allowing for scaling of DS-0 channel capacity.
|
Integrated Gigabit Ethernet Ports |
● All onboard WAN ports are 10/100/1000 Gigabit Ethernet WAN routed ports.
● One of the three 10/100/1000 Ethernet WAN ports on the Cisco 2921 and 2951 supports Small Form-Factor Pluggable (SFP)-based connectivity in lieu of a RJ-45 port and enabling fiber connectivity.
|
Innovative Universal-Serial-Bus (USB)-Based Console Access |
● A new, innovative USB console port offers management connectivity for devices without a serial port such as modern laptop computers.
● Traditional console and auxiliary ports are also available.
|
Optional Integrated Power Supply for Distribution of PoE and Universal DC Power Supply |
● An optional upgrade to the internal power supply provides inline power (802.3af-compliant PoE and Cisco Inline Power) to integrated switch modules.
● On the Cisco 2911, 2921, and 2951, an optional DC power supply is available that extends deployment into central offices and industrial environments.
● On the Cisco 2911, an optional DC-PoE power supply is available.
|
Optional External Redundant Power Supply (RPS) |
● The Cisco 2911, 2921, and 2951 allow for power redundancy through the use of an external RPS device, thereby decreasing network downtime and protecting the network from power-supply failures.
● Redundant power on the Cisco 2900 Series is supported through the Cisco RPS 2300 Redundant Power System. You can use the Cisco RPS 2300 to provide redundant power for Cisco 2900 Series ISRs as well as Cisco Catalyst® switches.
● In order to use the Cisco RPS 2300, an external RPS adapter is required (configurable option) to connect the platform to the external RPS.
|
PoE Boost |
● When connected to an external RPS device, the Cisco 2911, 2921, and 2951 can operate in a PoE boost configuration in lieu of redundant power mode – whereby the power capacity of the platform is increased to twice the normal level to power additional PoE ports.
|
Designed for Flexible Deployments |
● The Cisco 2911 and 2951 are designed for NEBS environments.
● The 2911 is 12” deep and has an optional fan filter for deployments in a variety of environments. An assembly that provides front-to-back airflow is also available for 23” racks.
