Architectural Feature

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 with Security

Sockets Layer (IPSec/SSL) 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 (both IPSec and SSL 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 multigigabit 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 will be available in the future that extends deployment into central offices and industrial environments.

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.
