Architectural Feature
Benefits
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.

Feature
Benefits
Cisco Enhanced High Speed WAN
Interface Card (EHWIC)
●
The EHWIC slot replaces the high-speed WAN interface card (HWIC) slot and can natively support
HWICs, WAN interface cards (WICs), wireless WAN 3G/4G LTE, voice 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 Module
(ISM)
●
A single ISM Slot provides flexibility to integrate intelligent services 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.
Compact Flash Slots
●
Two external Compact Flash slots are available on the Cisco 1941. 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.
