Product Review

The CISCO3925-HSEC+/K9 offers a comprehensive solution for secure, high-speed data, voice, and video communication with its inclusion of the VPN ISM module HSEC bundles tailored for the 3925 ISR platform. However, it occupies 3U of rack space and requires careful consideration for deployments where rack space is at a premium. Its versatility is highlighted by several expansion options, including 3 integrated Gigabit Ethernet ports, multiple service module slots, and support for up to 64 digital ports, but this complexity might necessitate a steep learning curve for network engineers not familiar with Cisco's ecosystem.


The CISCO CISCO3925-HSEC+/K9 is a highly capable router designed for the Integrated Services Router (ISR) platform, specifically tailored for secure communications with a high-performance throughput. This modular router is engineered to support a wide range of network interfaces and is packaged in a 3U size for desktop or rack-mounting, making it versatile for different deployment scenarios. At the core of the CISCO3925-HSEC+/K9 is the Services Performance Engine (SPE) module with SPE 100, providing the processing power necessary to handle demanding network tasks. The router is equipped with three integrated 10/100/1000 Ethernet ports, two of which offer dual RJ-45 or SFP connectivity options, supporting a variety of network media types. Expansion capabilities are significant with this model, featuring: - Two service module slots for additional hardware components. - One Internal Services Module slot for enhanced feature integration. - Four onboard digital signal processor (DSP) slots for voice and video processing. - Four Enhanced High-Speed WAN Interface Card (EHWIC) slots for network interface expansion. The router's connectivity technology is wired, ensuring reliable and secure data transmission. It adheres to IEEE standards such as 802.1Q, 802.1ah, and 802.1ag, which are critical for network segmentation, backbone bridging, and fault management, respectively. For monitoring and management, the router includes LED status lights indicators for link activity and power status. The device supports diverse interfaces, including three 10Base-T/100Base-TX/1000Base-T ports, management ports in both RJ-45 and mini-USB Type B formats, a serial auxiliary port, and two 4 PIN USB Type A ports for additional connectivity options. Furthermore, it offers two SFP (mini-GBIC) slots for fiber optic connections. The voice/fax module accommodates up to 64 digital ports, allowing for substantial voice communications capabilities. The router's expansion slots are well-appointed, with availability for HWIC, PVDM, CompactFlash Card, and an additional expansion slot, offering ample room for customization and scalability. Powering the CISCO3925-HSEC+/K9 is an internal power supply that operates within a voltage range of AC 120 V to AC 230 V and supports an input frequency of 50/60 Hz, making it adaptable to various power sources worldwide. The physical dimensions of the router are 47.6 cm in width, 43.8 cm in depth, and 8.9 cm in height, requiring three rack units (3U) in a standard equipment rack if not used in a desktop configuration. In summary, the CISCO CISCO3925-HSEC+/K9 offers a comprehensive set of features for secure and efficient network operations, including versatile connectivity options, significant expansion capabilities, and compliance with key networking standards. Its modular design and internal power supply support a range of network applications and deployment scenarios, making it a suitable choice for enterprise networks requiring robust performance and scalability.
