Dual Gigabit Ethernet Connectivity
The CISCO1941/K9 provides two integrated Gigabit Ethernet interfaces, delivering high-speed connectivity between the router and connected network infrastructure.
The Gigabit Ethernet ports can be used for connections to:
- LAN switches
- Enterprise networks
- Branch-office infrastructure
- WAN Ethernet services
- Servers and other network equipment
- Upstream routers or network appliances
The two integrated interfaces provide flexibility for different network designs without requiring an additional Ethernet expansion module.
Two EHWIC Expansion Slots
The Cisco 1941 includes two Enhanced High-Speed WAN Interface Card (EHWIC) slots.
These expansion slots allow compatible Cisco EHWIC modules to be installed to provide additional connectivity options according to the requirements of the deployment.
The modular architecture is particularly useful for branch networks where WAN technologies or interface requirements can vary between locations.
512 MB DRAM
This configuration is equipped with 512 MB of DRAM, providing memory resources for Cisco IOS operation, routing processes, and supported network services.
The available DRAM should be considered when selecting the appropriate IOS release and feature configuration for the intended deployment.
256 MB CompactFlash
The router includes 256 MB of CompactFlash (CF) storage.
CompactFlash storage is used for Cisco IOS software images and other files associated with the router’s operation. The available capacity provides storage for the software and related files, subject to the installed IOS release and configuration.
IP Base Software
The CISCO1941/K9 configuration includes IP Base software, providing foundational IP routing and networking functionality.
The exact features available depend on the installed Cisco IOS release and licensing configuration. Organizations requiring additional advanced functionality should verify the applicable software license and IOS feature set before deployment.
Modular Design
A major advantage of the Cisco 1941 platform is its modular architecture.
The two EHWIC slots provide options for expanding the router’s connectivity with compatible Cisco modules. This makes the platform adaptable to changing networking requirements and existing Cisco infrastructure.
Branch Office Networking
The CISCO1941/K9 is designed to serve as a routing platform for branch and remote-office networks.
Typical applications include:
- Branch-office routing
- Remote-site connectivity
- Small-business networks
- Enterprise branch networks
- WAN connectivity
- Network infrastructure replacement
- Cisco networking laboratories
- Training and educational environments
Cisco IOS Platform
The Cisco 1941 operates using the Cisco IOS networking platform, providing administrators with a familiar environment for router configuration and management.
Depending on the installed software release and license, Cisco IOS can provide routing, interface management, network services, and other supported functionality.
Flexible Connectivity
The combination of 2 Gigabit Ethernet ports and 2 EHWIC slots provides a balance between integrated connectivity and modular expansion.
Organizations can use the built-in Gigabit Ethernet interfaces for standard network connections while adding compatible EHWIC modules when additional WAN or interface functionality is required.
Professional Deployment
The Cisco 1941 is suitable for organizations looking for a modular Cisco routing platform for branch and remote-site environments.
Its hardware configuration provides a combination of:
- High-speed Ethernet connectivity
- Modular WAN expansion
- Dedicated Flash storage
- 512 MB system memory
- Cisco IOS-based routing
- Flexible deployment options
