Overview
The Cisco ISR4351K9 is a versatile router designed to meet the demands of midsize and large enterprise operations. With its advanced features and scalable options, it offers an efficient solution for managing network traffic and ensuring secure connectivity.
This model starts with an aggregate throughput of 200 Mbps, which can be increased to 400 Mbps with the performance license. For operations requiring high-speed data processing, the router also supports over 2 Gbps of aggregate CEF only throughput, making it suitable for handling large volumes of data efficiently.
The hardware includes three onboard WAN or LAN 10/100/1000 ports, providing flexibility in connecting to different network types without the need for additional modules. Additionally, it features three RJ-45 ports and three SFP ports, enabling it to support a wide range of connectivity options including fiber and copper links.
For expanding its capabilities, the ISR4351K9 is equipped with two enhanced service module slots and one doublewide service module slot, which can be used when no singlewide SM-X modules are installed. It also offers three NIM slots, further extending its functionality to meet specific network requirements.
Support for Online Insertion and Removal (OIR) ensures that the router can maintain continuous operation, even when modules are being added or replaced. The presence of an onboard ISC slot adds to its configurability, providing an additional option for customization.
The device comes with 4 GB of DDR3 RAM, which can be expanded up to 16 GB to accommodate more demanding applications. Similarly, its default flash memory of 4 GB can also be increased to 16 GB, offering ample space for software and configuration files.
Connectivity options are further enhanced with two external USB 2.0 Type A slots and one USB Type B mini slot, facilitating easy file transfer and system updates. A serial console port and a serial auxiliary port are included for management and troubleshooting purposes.
Power supply options are comprehensive, with internal AC, DC, and PoE available to suit various operational environments. The router operates within a voltage range of 100 to 240 VAC and has a typical power consumption of 48 W, making it energy efficient.
Measuring 3.5 x 17.25 x 18.5 inches and occupying 2 rack units (RU) in height, the ISR4351K9 is designed for rack-mount installation, allowing for efficient use of space in equipment rooms or data centers. It operates within a temperature range of 0 °C to 40 °C, ensuring reliable performance under standard working conditions.
