Chapter 1 Cisco 7200 VXR Product Overview

Field-Replaceable Units

Adjacent to the power supply bays are two chassis grounding receptacles that provide a chassis ground connection for ESD equipment or a two-hole grounding lug. (See Figure 1-4.)

Three internal fans draw cooling air into the chassis and across the internal components to maintain an acceptable operating temperature. (See Figure 1-4.) The three fans are enclosed in a tray that is located inside the chassis.

Caution To ensure the proper flow of cooling air across the internal components, make sure blank port adapters are installed in unoccupied port adapter slots, and power supply filler plates are installed in unoccupied power supply bays.

The I/O controller, port adapters, Port Adapter Jacket Card, power supplies, and network processing engine or network services engine slide into their respective chassis slots and connect directly to the router’s midplane; there are no internal cables to connect. The midplane distributes power from the power supplies to the I/O controller, port adapters, Port Adapter Jacket Card, fan tray, and network processing engine or network services engine.

The midplane also senses OIR of the port adapters, bridges the PCI buses from the port adapters to packet memory on the network processing engine or network services engine, arbitrates traffic across the PCI buses, and generates the clock signals for the port adapters on each PCI bus.

Note The Port Adapter Jacket Card does not support OIR. However, the port adapter installed in the Port Adapter Jacket Card does support OIR.

The Cisco 7206VXR operates as either a tabletop or a rack-mounted unit. A rack-mount kit is standard equipment included with all Cisco 7200 VXR routers when they are shipped from the factory. The kit provides the hardware needed to mount the router in a standard 19-inch equipment rack or a 2-post rack. Steps for installing the Cisco 7206VXR router in an equipment rack are the same for all Cisco 7200 VXR routers and are explained in Chapter 3, “ Installing a Cisco 7200 VXR Router.” If you are not rack-mounting your Cisco 7206VXR, place it on a sturdy tabletop or platform.

A fully configured Cisco 7206VXR, with two installed power supplies and all chassis slots filled, weighs approximately 50 pounds (22.7 kilograms [kg]). For clearance requirements and rack-mount installation considerations, see Chapter 2, “Preparing for Installation,” the “Site Requirement Guidelines” section on page 2-3.

7200 VXR specifications

The Cisco Systems 7200 VXR Series is a robust and highly scalable modular router designed to meet the demands of service providers and enterprises seeking high-performance solutions for their network infrastructures. Launched as part of the Cisco 7200 series, the VXR (Virtual Extensible Routing) variant enhances capabilities while providing effective support for a wide range of applications, including Internet Protocol (IP) routing, Voice over IP (VoIP), and Virtual Private Network (VPN) configurations.

At the core of the 7200 VXR is its modular design, which enables network administrators to customize the router according to their specific needs. The router supports a variety of interface cards, processing engines, and power supply options, ensuring flexibility for diverse network environments. This modularity facilitates easy upgrades and expansions, making it ideal for growing enterprises and service providers looking to future-proof their networks.

One of the standout features of the Cisco 7200 VXR is its impressive routing performance. It can handle a high level of traffic with low latency, which is critical for bandwidth-intensive applications. The router supports a wide array of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Integrated Intermediate System-to-Intermediate System (IS-IS), providing versatility for various network topologies.

The 7200 VXR also incorporates advanced features for enhanced security and reliability. With support for IPsec VPNs, it enables secure data transmission across untrusted networks. The router also includes features like Quality of Service (QoS) for prioritizing network traffic, ensuring critical applications receive the bandwidth they require even during peak loads.

In terms of scalability, the Cisco 7200 VXR can support hundreds of thousands of routes and MAC addresses, making it suitable for large metropolitan area networks (MANs) as well as enterprise backbone applications. It also provides the capability to support IPv4 and IPv6 networks, preparing organizations for a transition to next-generation internet protocols.

Additional characteristics of the Cisco 7200 VXR include enhanced manageability through the Cisco IOS software, which offers a comprehensive command-line interface and support for network management protocols. The router is also energy-efficient, with options for redundant power supplies that ensure continuous availability and minimal downtime in mission-critical applications.

Overall, the Cisco Systems 7200 VXR represents a powerful solution that combines performance, scalability, and security, making it an excellent choice for organizations looking to enhance their network capabilities in a rapidly evolving technological landscape.
