The Cisco 3900 Datasheet is a vital document for anyone looking to understand the capabilities and specifications of the Cisco 3900 Series Integrated Services Routers. This comprehensive resource acts as a blueprint, detailing everything from hardware components to software features, and is essential for network professionals, IT decision-makers, and anyone involved in deploying or managing network infrastructure. Understanding the Cisco 3900 Datasheet is key to making informed decisions about network design and optimization.
What is the Cisco 3900 Datasheet and How is it Used?
At its core, the Cisco 3900 Datasheet is a technical specification document published by Cisco Systems. It provides an in-depth look at a specific hardware product, in this case, the Cisco 3900 Series ISRs. These routers are designed to deliver a wide range of network services, including secure connectivity, high-performance data, and voice transport. The datasheet outlines the various models within the 3900 series, such as the 3925, 3945, and 3945E, highlighting their unique strengths and intended applications. Think of it as the instruction manual and feature list all rolled into one, giving you a complete picture of what the router can do.
The primary use of the Cisco 3900 Datasheet is to assist in the planning, selection, and deployment of these routers. Network engineers rely on it to verify if a particular router meets the required performance metrics, such as throughput, latency, and port density. For instance, a network administrator might need to ensure a router supports a specific number of simultaneous voice calls or can handle a certain volume of data traffic. The datasheet provides these critical figures, allowing for accurate capacity planning and avoiding over-provisioning or under-provisioning of network resources. It also details:
- Hardware specifications: Including modularity, memory options, and power supply details.
- Performance metrics: Such as forwarding rates and integrated services capabilities.
- Connectivity options: Such as available interfaces and their speeds (e.g., Gigabit Ethernet, Serial).
- Security features: Detailing built-in security capabilities like firewall and VPN support.
- Supported services: Information on voice, video, and data services the router can handle.
Furthermore, the Cisco 3900 Datasheet is invaluable for understanding the scalability and future-proofing aspects of the 3900 series. It often details the modular design, which allows for the addition of Network Modules (NMs) and services modules. This means that as network needs evolve, the router can be upgraded without requiring a complete replacement. The datasheet will typically list the types of modules supported, such as:
- Enhanced EtherSwitch® services modules
- Security features modules
- High-density digital signal processor (DSP) modules
This level of detail is crucial for making long-term investments in network infrastructure. The ability to tailor the router's capabilities to specific business needs, supported by the clear specifications in the datasheet, is paramount for achieving optimal network performance and return on investment. Without this document, selecting the right router and configuring it for maximum effectiveness would be a significant challenge.
To get the most accurate and up-to-date information about the Cisco 3900 Series Integrated Services Routers, it is highly recommended to consult the official Cisco 3900 Datasheet. This resource will provide all the technical specifications, features, and compatibility details you need.
