Cisco 1900 Series
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). The table below lists the
architectural features and benefits of the Cisco 1941 Series.
Architectural Feature Description
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.
• The Cisco 1941 introduces an innovative MultiGigabit Fabric (MGF) which
MultiGigabit Fabric
allows for efficient module to module communication, enabling direct
services interactions across modules while reducing the overhead on the
router processor.
Embedded IPsec/ • Embedded hardware encryption acceleration is enhanced to provide
higher scalability, which, combined with an optional Cisco IOS Security
SSL VPN Hardware
Acceleration license, enables WAN link security and VPN services (Both IPsec and SSL
acceleration).
Integrated Gigabit • All onboard WAN ports are 10/100/1000 Gigabit Ethernet
Ethernet Ports WAN routed ports.
Innovative universal- • A new, innovative, mini-B USB console port supports management
serial-bus (USB)-based connectivity when traditional serial ports are not available.
console access
• 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 • An optional upgrade to the internal power supply provides in-line power
Supply for Distribution of (802.3af-compliant Power-over-Ethernet [PoE] and Cisco standard inline
Power Over Ethernet (PoE) 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. 1 1n draft 2.0 standard
that uses MIMO (Multi-Input, Multiple-output) to improve coverage for
existing 802. 1 1a/ b/g clients and new 802. 1 1n clients.
• The Cisco 1941 supports dual radios-802. 1 1 b/g/n and 802. 1 1a/n and is
capable of operating in both autonomous and unified modes.

Modularity Features and Benefits
The Cisco 1941 provides significantly enhanced modular capabilities 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.

Benefit Description
• The EHWIC slot replaces the high-speed WAN interface card (HWIC)
Cisco Enhanced High
Speed WAN Interface slot and can natively support HWICs, WAN interface cards (WICs), voice
Card (EHWIC) interface cards (VICs), and voice/WAN interface cards (VWICs)
• Two integrated EHWIC slots are available on the Cisco 1941 for flexible
configurations for support of two modules: One double wide HWIC-D or
single wide EHWIC/HWIC module and a second single wide E-HIC/HWIC
module are supported
• Each HWIC Slot offers high data throughput capability
• Up to 1.6 Gbps aggregate towards the router processor
• Up to 2 Gbps aggregate to other module slots over MultiGigabit
Fabric (MGF)
Cisco Internal Services • A single ISM Slot provides flexibility to integrate intelligent services
Module (ISM) modules that do not require interface ports.
• ISM replaces the Advanced Integration Module (AIM) slot, existing AIM
modules are not supported in the ISM slot
• Each ISM Slot offers high data throughput capability
• Up to 4 Gbps aggregate towards the router processor
• Up to 2 Gbps aggregate to other module slots over MultiGigabit Fabric
(MGF)
• Power to ISM slots can be managed by extensions similar to the Cisco
EnergyWise framework, allowing organizations to reduce energy
consumption in their network infrastructure. Full EnergyWise support will
be available in future software releases.
Note: The Cisco 1941 cannot have ISM and WLAN on the same chassis.
Please refer to ordering information for WLAN SKUs
• Two external Compact Flash slots are available on the Cisco 1941.
Compact Flash Slots
Each slot can support high-speed storage densities upgradeable to
4GB in density.
USB 2.0 Ports • Two high-speed USB 2.0 ports are supported. The USB ports enable
another mechanism secure token capabilities and storage.
