Overview
The Cisco ISR4221K9 is a network router designed for small to medium-sized businesses, featuring a range of capabilities to facilitate efficient and secure data transmission across networks. This product stands out due to its scalability and flexibility, accommodating various throughput requirements and connectivity options. The base configuration of the ISR4221K9 offers an aggregate throughput of 35 Mbps, which can be significantly increased with licensing upgrades. With the Performance License, the throughput can be boosted to 300 Mbps, and for even more demanding network environments, the Boost License elevates the aggregate CEF (Cisco Express Forwarding) only throughput to over 1.2 Gbps.
Connectivity options are versatile, with the router providing two onboard WAN or LAN 10/100/1000 ports for high-speed internet connections. Additionally, it includes:
- Two RJ-45 ports for direct, wired connections to other network devices.
- One SFP port for fiber optic connections, offering a secure and fast data transmission option.
- Three NIM (Network Interface Module) slots, enhancing the router's functionality by allowing for the addition of various interface cards.
The ISR4221K9 does not support OIR (Online Insertion and Removal), meaning any upgrades or maintenance requiring module changes will necessitate powering down the unit. Its memory capacity includes 4 GB of DDR3 RAM, which is the maximum supported, ensuring smooth operation of the installed IOS (Internetwork Operating System) and running processes. For external storage and firmware upgrades, the router is equipped with two USB 2.0 Type A slots.
Management and configuration of the device are facilitated through a single serial console port, which doubles as a CON/AUX port, allowing for direct access to the router's command-line interface. The ISR4221K9 is powered by an external AC power supply, accepting an input voltage range from 100 to 240 VAC. With a typical power consumption of 24 W, it is designed to operate efficiently, minimizing operational costs.
Physically, the router dimensions are set at 1.72 x 12.7 x 10 inches, making it compact enough to fit in a 1 RU (Rack Unit) space within a standard 19-inch rack. This size and form factor make it an ideal choice for businesses with limited space but needing reliable network infrastructure. The operating temperature range is from 0 °C to 40 °C, ensuring reliability and performance even in varying environmental conditions.
In summary, the Cisco ISR4221K9 is a versatile and scalable router that caters to a range of business networking needs. Its upgradeable throughput options, combined with multiple connectivity ports and a compact, efficient design, make it a valuable asset for any small to medium-sized enterprise looking to maintain or enhance its network performance and reliability.

Product Review
The Cisco ISR4221K9 offers scalable performance, starting with a default aggregate throughput of 35 Mbps, which can be increased to 300 Mbps with a Performance License and over 1.2 Gbps with a Boost License, catering to a wide range of networking demands. However, its hardware is limited to 2 RJ-45 ports, a single SFP port, and no support for Online Insertion and Removal (OIR), which might restrict expansion possibilities and ease of maintenance in dynamic networking environments. Additionally, with only 4 GB of non-upgradable DDR3 RAM and a reliance on external AC power, the ISR4221K9 may face challenges in supporting memory-intensive applications and ensuring power redundancy for critical network operations.
