5ISR4461/K9 Description
Cisco ISR4461/K9, also referred to as ISR 4461 or Cisco 4461 router, is the flagship model of the Cisco 4000 Series Integrated Services Routers. It integrates 4 Gigabit Ethernet ports and 2 × 10 Gigabit SFP+ uplinks, together with 3 NIM slots and 3 SM-X slots for advanced service modules. With throughput scalable from 1.5 Gbps to 3 Gbps, the ISR4461 is engineered for very large branches, regional hubs, or campus edge deployments that demand secure WAN aggregation, voice, collaboration, and SD-WAN capabilities. With up to 32 GB DRAM, 32 GB flash, high PoE capacity, and redundancy options, it provides enterprise-grade resiliency and scalability.

Key Features
High-Capacity Branch and Hub Routing
Provides 1.5–3 Gbps aggregate throughput, enabling large branch offices, regional hubs, and campus edges to consolidate high-volume WAN traffic with ease.
Extensive Modularity for Service Integration
With 3 NIM slots and 3 SM-X slots, the ISR4461 supports WAN, security, UCS-E compute, and EtherSwitch modules, allowing enterprises to deploy tailored services on a single platform.
Advanced Collaboration and Voice Readiness
Integrated ISC slot for PVDM4 DSPs delivers SRST, conferencing, and secure transcoding, making the router a reliable UC gateway for distributed organizations.
Enhanced Security and SD-WAN Capabilities
Hardware-accelerated VPN, IPSec, and Cisco SD-WAN functions provide encrypted tunnels, application visibility, and policy-based traffic control.
High PoE Capacity for Converged Access
Supports up to 1450 W PoE with a PoE PSU boost, powering large numbers of IP phones, access points, or surveillance devices directly from the chassis.
Enterprise Reliability and Scale
Redundant PSU options, field-replaceable modules, advanced IOS XE software, and extensive memory (up to 32 GB DRAM) ensure long-term stability and scalability for mission-critical deployments.
Application Scenarios
Designed for organizations that require multi-gigabit WAN throughput, integrated UC services, and secure SD-WAN connectivity across hundreds of users.
Provides compliance-grade VPNs, resilient voice and video, and high-density PoE for critical environments where downtime or data breaches are unacceptable.
Suitable for mission-critical sites needing converged voice, video, and data services, high PoE budgets for connected devices, and flexible WAN options in campus networks.
