Chapter 3 Installing a Cisco 7200 VXR Router

Connecting Port Adapter Cables

The instructions for connecting the cables for each port adapter installed in the Cisco 7200 VXR routers are contained in the respective configuration note for each port adapter. For example, if you are connecting the cables for a 4-port, Ethernet port adapter, refer to the configuration note PA-4E Ethernet 10BaseTPort Adapter Installation and Configuration. The document is available on the Documentation DVD and on Cisco.com.

Instructions for securing port adapter interface cables to the cable-management brackets are contained in the “Installing the Cable-Management Brackets” section on page 3-15.

Connecting I/O Controller, NPE-G1, or NPE-G2 Cables

This section contains connection equipment and pinout information for the Ethernet, Fast Ethernet, Gigabit Ethernet, console, and auxiliary ports that are located on the I/O controller, NPE-G1, or NPE-G2. If you have an NPE-G1 or NPE-G2 installed, you do not need an I/O controller, although an I/O blank panel must be in place if you remove the I/O controller.

The NPE-G1 or NPE-G2 has three Gigabit Ethernet interfaces and six ports; three RJ-45 ports and three GBIC module ports (NPE-G1) or four SFP module ports (NPE-G2). It also has an auxiliary and a console port. See the “RJ-45 Port Cabling and Pinouts” section on page 3-37for information about the RJ-45 console and auxiliary ports. Additionally, the NPE-G2 has a Fast Ethernet Management port.

Note You can install the C7200-I/O and C7200-I/O-FE I/O controllers in Cisco 7200 VXR routers, including a Cisco 7206VXR router shelf in a Cisco AS5800 Universal Access Server.

Connecting to Gigabit Ethernet Slots and Ports

The NPE-G2, the NPE-G1, and C7200-I/O-GE+E I/O controller have Gigabit Ethernet slots and ports.

•The NPE-G2 has three Gigabit Ethernet interfaces; four SFP module ports and 3 RJ-45 ports. Any three of the six can be used at the same time.

•The NPE-G1 has three Gigabit Ethernet interfaces; three GBIC module ports and three RJ-45 ports. Any three of the six can be used at the same time.

•The C7200-I/O-GE+E I/O controller has one GBIC slot and one Fast Ethernet RJ-45 port.

For further information and specifications, see the Gigabit Interface Converter GBIC Module and Small Form-Factor Pluggable (SFP) GBIC Module Installation Instructions and Specifications

This section contains information on both the GBIC and RJ-45 connections. See the “Gigabit Ethernet GBIC Connections” section on page 3-24or the “Gigabit Ethernet RJ-45 Connections on the NPE-G1 and NPE-G2” section on page 3-29.

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.
