Cisco 4000 Series ISR Modules & Cards

Cisco 4000 Series Integrated Services Routers (ISRs) offer a wide range of modular modules and cards that extend the functionality and capabilities of the routers. These modules and cards provide additional services, connectivity options, and performance enhancements to meet the evolving networking needs of organizations. In this overview, we will focus on the hardware specifics of the Cisco 4000 Series ISR Modules and Cards. Form Factor: The Cisco 4000 Series ISR Modules and Cards are modular components designed to fit into the available slots on the Cisco 4000 Series routers. These modules and cards have a standardized form factor, ensuring easy installation, expansion, and removal without requiring additional rack space or external power supplies. Service Modules: The Cisco 4000 Series ISR offers various service modules that provide additional services and capabilities to the router. Some common service modules include: Network Interface Modules (NIMs): NIMs provide a variety of connectivity options such as Ethernet, T1/E1, T3/E3, DSL, and Serial interfaces. These modules enable routers to connect to different types of networks and devices. Enhanced Service Modules (ESMs): ESMs offer enhanced services like firewall, VPN acceleration, and intrusion prevention. These modules provide hardware acceleration and offload resource-intensive tasks from the router's main processor, improving performance and security. Storage Networking Modules (SNMs): SNMs support storage area networking protocols such as Fibre Channel and Fibre Channel over Ethernet (FCoE). These modules enable the router to connect to storage devices and support storage replication and backup services. Voice Interface Cards (VICs): VICs provide voice connectivity options such as analog, digital, and IP telephony interfaces. These cards enable the router to support voice services and integrate with IP telephony systems. Network Interface Cards (NICs): Cisco 4000 Series ISR routers support Network Interface Cards (NICs), which offer additional connectivity options and expansion capabilities. These cards can provide Ethernet interfaces, allowing for increased network connectivity and flexibility. The NICs can support different speeds such as 1 Gigabit Ethernet (1GE) or 10 Gigabit Ethernet (10GE), depending on the specific card model. Power and Redundancy: The Cisco 4000 Series ISR Modules and Cards draw power from the router itself, eliminating the need for external power supplies. They support both single and dual-power options, providing power redundancy for uninterrupted operation. Dual-power options ensure continuous performance even in the event of a power supply failure. Compatibility: The Cisco 4000 Series ISR Modules and Cards are designed to be compatible with specific Cisco 4000 Series ISR router models. Each module or card is optimized for specific router platforms, ensuring seamless integration and optimal performance. Management and Monitoring: The Cisco 4000 Series ISR Modules and Cards are managed and monitored through the router's management interface, such as the Cisco IOS Software Command-Line Interface (CLI) or a graphical user interface (GUI) provided by the router's management software. This allows for centralized configuration, monitoring, and troubleshooting of the modules, cards, and the overall network. Expansion Slots: The Cisco 4000 Series ISR routers come with multiple expansion slots to accommodate the modules and cards. These expansion slots allow for the installation of additional modules, cards, or network interface modules to scale the router's functionality and connectivity as needed. The number of expansion slots varies depending on the specific router model. In summary, the Cisco 4000 Series ISR Modules and Cards provide organizations with enhanced services, connectivity options, and performance capabilities for their networking infrastructure. With their modular design, compatibility with Cisco 4000 Series ISR routers, power redundancy, and support for expansion slots, these modules and cards allow organizations to customize their router setup, meet their specific networking requirements, and scale their networks as needed.
