Benefits

Description

Service Integration

• The Cisco 1941 Series offer increased levels of services integration with data, security, wireless and mobility services enabling greater efficiencies cost savings.

Services on Demand

• A single Cisco IOS® Software Universal image is installed on each ISR G2. The Universal image contains all 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 1900 Series enables deployment in high speed WAN environments with concurrent services enabled up to 25 Mbps.
• Multi-Gigabit Fabric enables high bandwidth module to module communication without compromising routing performance

Network Agility

• Designed to address customer business requirements, Cisco 1941 Series with the modular architecture, offers performance range of modular interfaces and services as your network needs grow.
• Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.

Energy Efficiency

• The Cisco 1941 Series architecture provides energy savings features that include the following:
• The Cisco 1900 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 1941 Series maximizes investment protection by supporting:
• Reuse of a broad array of existing modules supported on the original Integrated Services Routers provides a lower cost of ownership
• Rich set of Cisco IOS Software features carried forward from the original Integrated Services Routers and delivered in the universal image.
• Flexibility to grow as your business needs evolve

Architecture & Modularity

The Cisco 1941 Series is architected to meet the application demands of today's branch offices with design flexibility for future applications. The modular architecture is designed to support expanding customer requirements, increased bandwidth, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE) and Cisco Enhanced PoE (ePoE). Table 2 lists the architectural features and benefits of the Cisco 1941 Series

Table 2. Architectural Features and Benefits

Architectural Feature

Benefits

Modular Platform

• The Cisco 1941 Series ISR are highly modular platforms with multiple module slots to provide connectivity and services for varied branch network requirements.
• The ISRs offer an industry-leading breadth of LAN and WAN connectivity options through modules to accommodate field upgrades to future technologies without requiring replacement of the platform.

Processors

• The Cisco 1941 Series is powered by high-performance multi-core processors that support growing demands of branch office networks by supporting high throughput WAN requirements.

MultiGigabit Fabric

• The Cisco 1941 introduces an innovative MultiGigabit Fabric (MGF) which allows for efficient module to module communication, enabling direct services interactions across modules while reducing the overhead on the router processor.

Embedded 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 out-performs the Advanced Integration Modules of previous generations.

Integrated Gigabit Ethernet Ports

• All onboard WAN ports are 10/100/1000 Gigabit Ethernet WAN routed ports.

Innovative universal-serial-bus (USB)-based console access

• A new, innovative, mini-B USB console port supports management connectivity when traditional serial ports are not available.
• The traditional console and auxiliary ports are also available. Either the USB-based console or the RJ-45-based console port can be used to configure the router.

Optional Integrated Power Supply for Distribution of Power Over Ethernet (PoE)

• An optional upgrade to the internal power supply provides in-line power (802.3af-compliant Power-over-Ethernet [PoE] and Cisco standard inline power) to optional integrated switch modules.

Integrated Wireless LAN

• The Cisco 1941 offers a secure integrated access point in a single device.
• Integrated access point is based on the IEEE 802.11n draft 2.0 standard that uses MIMO (Multi-Input, Multiple-output) to improve coverage for existing 802.11a/ b/g clients and new 802.11n clients.
• The Cisco 1941 supports dual radios-802.11 b/g/n and 802.11a/n and is capable of operating in both autonomous and unified modes.

Modularity Features and Benefits

The Cisco 1941 provides significantly enhanced modular capabilities (refer to Table 2) offering investment protection for customers. Most of the modules available on previous generations of Cisco routers, such as the Cisco 1841 ISR, are supported on the Cisco 1941. Additionally, modules used on the Cisco 1941 can easily be interchanged with other Cisco routers to provide maximum investment protection. Taking advantage of common interface cards across a network greatly reduces the complexity of managing inventory requirements, implementing large network rollouts, and maintaining configurations across a variety of branch-office sizes.
A complete list of supported modules is available at http://www.cisco.com/go/1941.
