Product Review

The CISCO ISR4461/K9 offers versatile connectivity options with its mix of RJ-45, SFP ports, and enhanced service module slots, catering to a wide range of network configurations. However, while its default aggregate throughput of 1.5 Gbps can be upgraded to 3 Gbps with a performance license, and even higher for CEF only traffic, this may still limit high-performance requirements in data-intensive environments. Additionally, the unit supports a substantial memory upgrade from 8 GB to 32 GB DDR3 RAM, accommodating advanced services and applications, but the initial cost and potential need for future upgrades should be carefully considered.


The CISCO ISR4461/K9 is a high-performance integrated services router designed to meet the demands of enterprise and service provider networks. It features significant enhancements in throughput, port capacity, and memory, making it a versatile solution for environments requiring reliable, high-speed data processing and transmission. At its core, the ISR4461/K9 offers an aggregate throughput of 1.5 Gbps, which can be upgraded to 3 Gbps with a performance license. For operations prioritizing Cisco Express Forwarding (CEF), the router can achieve throughput of over 7 Gbps, showcasing its capability to handle intensive data traffic efficiently. Connectivity options are ample, with the device equipped with four onboard WAN or LAN 10/100/1000 ports. This is complemented by four RJ-45 ports and an equal number of SFP ports, allowing for flexible network configurations and easy integration into diverse network architectures. The inclusion of three Enhanced Service Module slots and two doublewide service module slots further extend its functionality, enabling the addition of voice, video, security, and data services. Networking infrastructure modularity is a key aspect of the ISR4461/K9, supported by three Network Interface Module (NIM) slots. These slots accommodate a variety of NIMs, providing options for increased port density, diverse connection types, and advanced network services. The router also supports Online Insertion and Removal (OIR), minimizing downtime during upgrades or module exchanges. For management and connectivity, the device features one onboard ISC slot, two external USB 2.0 Type A slots, and one USB Type B mini slot. A serial console port and a serial auxiliary port are present for local system access and troubleshooting. The ISR4461/K9 comes with 8 GB of DDR3 RAM for the control and services plane, upgradable to 32 GB, ensuring efficient processing and multitasking capabilities. Flash memory starts at 8 GB and can also be expanded to 32 GB, providing ample storage for operating systems, applications, and data. Power supply options are versatile, with internal AC, DC, and PoE choices to suit various deployment scenarios. The router operates within a wide AC input voltage range of 100 to 240 VAC and has a typical power consumption of 158 W, balancing performance with energy efficiency. Designed for rack mounting, the ISR4461/K9 measures 3.5 x 17.25 x 18.5 inches, fitting standard server racks and cabinets. Its operating temperature ranges from 0 °C to 40 °C, and it can function in environments with relative humidity levels between 5% and 85%, ensuring reliability in varying conditions.
