Product Review

The CISCO3925-V/K9 offers a comprehensive set of interfaces and ports, including 3 integrated 10/100/1000 Ethernet ports, multiple expansion slots for service modules, and digital signal processor (DSP) slots, catering to versatile networking needs. However, with only 1 GB of DRAM memory installed (expandable to 2 GB) and 256 MB of flash memory (expandable to 8 GB), the initial memory capacity might be limiting for high-throughput environments. Additionally, its 3U rack space requirement and internal power supply that supports a wide voltage range accommodate easy integration into existing network infrastructures, but the physical dimensions and power requirements may necessitate careful planning in space-constrained setups.


The CISCO3925-V/K9 is a versatile and powerful router designed for mid-sized to large businesses requiring high levels of data communication and processing. This model is housed in a 3U rack unit, making it suitable for standard rack mounting in data centers and server rooms. It is engineered to support a wide range of network infrastructure needs, from complex enterprise applications to high-volume data transfer and voice services. At the core of its connectivity capabilities, the CISCO3925-V/K9 boasts three integrated 10/100/1000 Ethernet ports. Two of these ports offer dual functionality, supporting both RJ-45 connectors and SFP (Small Form-factor Pluggable) modules, providing flexibility in network design and connectivity options. This dual capability ensures that the router can adapt to various network architectures, whether they rely on copper cabling or fiber optics. The router is equipped with an array of expansion slots to enhance its functionality and adaptability. These include two service module slots, one Internal Services Module (ISM) slot, four onboard digital signal processor (DSP) slots, and four Enhanced High-Speed WAN Interface Card (EHWIC) slots. This array of slots allows for significant customization and scalability, enabling businesses to tailor the router to their specific needs, whether that's expanding voice capabilities, adding security features, or increasing processing power.
  • Compliant with IEEE standards 802.1Q, 802.1ah, and 802.1ag, ensuring compatibility with a wide range of networking protocols and methodologies.
  • Equipped with 1 GB of DRAM memory, expandable up to 2 GB, and 256 MB of flash memory, expandable up to 8 GB, facilitating robust performance and ample storage for operating systems and applications.
  • Features a variety of management and connectivity interfaces, including RJ-45 console ports, mini-USB Type B console ports, auxiliary ports, USB Type A ports, and two SFP ports, providing comprehensive control and connectivity options.
For monitoring and diagnostics, the router includes LED status lights indicators for link activity and power status, helping administrators quickly assess the router's operational state. The voice/fax module supports up to 64 digital ports, making this router particularly suitable for organizations that rely on extensive voice communication capabilities. The power supply is internal, requiring an AC voltage between 120 V and 230 V and is compatible with a 50/60 Hz input frequency, accommodating a wide range of global power standards. The physical dimensions of the router are 47.6 cm in width, 43.8 cm in depth, and 8.9 cm in height, ensuring it fits within standard rack configurations. In summary, the CISCO3925-V/K9 is a comprehensive solution for businesses looking for a scalable, flexible, and high-performance networking platform. Its array of ports and expansion slots, combined with its compliance with key IEEE standards, robust memory options, and versatile power requirements, make it an excellent choice for organizations aiming to bolster their networking infrastructure.
