The Cisco ASR 920 Datasheet is a critical document for anyone involved in network design, deployment, or maintenance. This comprehensive resource provides the in-depth technical specifications and operational details necessary to understand the capabilities and limitations of the Cisco ASR 920 Series routers. Whether you're a network engineer, a solutions architect, or a procurement specialist, mastering the information within the ASR 920 Datasheet is key to making informed decisions.
What is the ASR 920 Datasheet and How is it Used?
The ASR 920 Datasheet is essentially a detailed technical blueprint for the Cisco ASR 920 Series routers. It outlines everything from the physical dimensions and power requirements of the hardware to the software features and supported protocols. Think of it as the user manual for network professionals, providing the granular details needed to understand how these devices function and what they can achieve within a network infrastructure. This includes information on memory, processor speed, port configurations, environmental operating conditions, and the various hardware and software options available. The importance of the ASR 920 Datasheet cannot be overstated, as it forms the foundation for accurate network planning and resource allocation.
Network engineers rely heavily on the ASR 920 Datasheet for several key purposes. Firstly, it helps in selecting the right configuration of the ASR 920 for a specific application. For instance, if a particular service requires a certain throughput or a specific set of interface types, the datasheet will clearly indicate whether the ASR 920, in its various models and configurations, can meet those demands. It also plays a crucial role in capacity planning, allowing engineers to determine how many routers are needed and what their aggregate performance will be. This leads to efficient use of resources and avoids costly over-provisioning or under-provisioning.
The use cases for the ASR 920 Datasheet extend beyond initial deployment. During troubleshooting, it can be an invaluable resource to verify hardware capabilities or understand the limitations of certain software features. For procurement teams, the datasheet provides the precise specifications needed to solicit accurate quotes and ensure that the purchased equipment aligns with the technical requirements. Here's a glimpse of the kind of information you'll typically find:
- Performance Metrics: Throughput, latency, and jitter characteristics.
- Interface Specifications: Types (e.g., Ethernet, SFP+), speeds, and quantities.
- Power Consumption and Requirements: Voltage, wattage, and redundant power supply options.
- Environmental Specifications: Operating temperature, humidity, and altitude limits.
- Software Features: Supported protocols (e.g., BGP, OSPF), Quality of Service (QoS) capabilities, and security features.
This detailed breakdown allows for informed decision-making across the entire network lifecycle. For example, a small table might illustrate the differences in port densities across various ASR 920 models:
| Model | Gigabit Ethernet Ports | 10 Gigabit Ethernet Ports |
|---|---|---|
| ASR 920-10G | 8 | 2 |
| ASR 920-20G | 16 | 4 |
