ISR4461/K9 Routers Overview
The ISR4461/K9 is the Cisco ISR 4461 router, offering 4 onboard GE ports, 3 NIM slots, 1 ISC slot, and 3 SM slots for flexible deployment options. It comes with 8 GB Flash Memory (default) and 2 GB DRAM (default for data plane), along with 4 GB DRAM (default for control plane). The Cisco 4000 Series Integrated Services Routers (ISR) revolutionize WAN communications for enterprise branch locations, offering built-in intelligent network capabilities and convergence. These routers are designed to meet the growing demand for application-aware networking in distributed enterprise sites, which often have lean IT resources but require direct communication with both private data centers and public clouds across diverse links like MPLS VPNs and the Internet.
With 1.5Gbps aggregate throughput, the ISR4461/K9 is capable of handling demanding workloads. It features 4 onboard WAN or LAN 10/100/1000 ports, 4 SFP-based ports, and 2 onboard 10Gbps ports for high-speed connectivity. Additionally, the router supports 3 enhanced service-module slots, 2 doublewide service-module slots, and 3 NIM slots for further customization. The ISR4461/K9 also includes 1 onboard ISC slot and supports OIR (all I/O modules) for easy hot-swapping. With a rack-mountable 2RU form factor, the router is ideal for enterprise environments. Shop Cisco Routers like the ISR4461-K9 for Cisco Enterprise Branch Routers, offering service module support, network interface module support, ISC onboard, SFP-based connectivity, PoE, and I/O module support, with 1.5Gbps router performance.
