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) |

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.
