Investment protection ● The Cisco 1921 maximizes investment protection by supporting:
●
The Cisco 1921 architecture provides energy-savings features that include the following:
●
The Cisco 1900 Series offers intelligent power management and allows you 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 TCO, including materials and energy use.
●
High-efficiency power supplies are provided with each platform.
●
Reuse of a broad array of existing modules supported on the original integrated services routers (ISRs) provides a lower
TCO.
●
A rich set of Cisco IOS Software features is carried forward from the original ISRs and delivered in the universal image.
●
This router gives you the flexibility to grow as your business needs evolve.
Architecture and Modularity
The Cisco 1921 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 PoE and Cisco Enhanced PoE
(ePoE). Table 2 lists the architectural features and benefits of the Cisco 1921.

●
The Cisco 1921 ISRs are highly modular platforms with multiple module slots to provide 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 to future technologies without requiring replacement of the platform.
●
The Cisco 1921 is powered by high-performance multicore processors that support growing demands of branch-office
networks by supporting high-throughput WAN requirements.
●
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.
●
All onboard WAN ports are 10/100/1000 Gigabit Ethernet WAN-routed ports.
●
A new, innovative, mini-Type B USB console port supports management connectivity when traditional serial ports are
not available.
●
The traditional console and auxiliary ports are also available. You can use either the USB-based console or the RJ45-based console port to configure the router.
●
An optional upgrade to the power supply provides inline power (802.3af-compliant PoE and Cisco Standard Inline
Power to optional integrated switch modules.
Modularity Features and Benefits
The Cisco 1921 provides significantly enhanced modular capabilities (refer to Table 3) that offer you investment
protection. Most of the modules available on previous generations of Cisco routers, such as the Cisco 1841 ISR, are
supported on the Cisco 1921. Additionally, you can easily interchange modules used on the Cisco 1921 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.
