Chapter 5 Troubleshooting the Installation

Troubleshooting the Processor Subsystem

Troubleshooting the Network Processing Engine or Network Services Engine

The procedures in this section assume that the I/O controller, network processing engine or network services engine, and router itself are in the original factory configuration, and that you have not made changes to your configuration file. Also see the troubleshooting chapter of the Network Processing Engine and Network Services Engine Installation and Configuration guide for the network services engine Parallel eXpress Forwarding (PXF) processor information.

If the I/O controller ENABLED LED does not go on as expected, make sure the power to the router is turned off, reseat the network processing engine or network services engine in its slot, and restart the router.

If the ENABLED LED remains off, the system detected a processor hardware failure. (This LED should be on in normal operation.) Contact a service representative for instructions.

Troubleshooting the Port Adapter Jacket Card

Check the following to help isolate a problem with the Port Adapter Jacket Card:

Is the PWR (power) LED on?

If yes, the system is operational.

If no, check to be sure that power is turned on to the system. For a DC-powered system, check to make sure that power has not been turned off at the power source. Then check to be sure that the Port Adapter Jacket Card has not pulled away from the backplane. Power down the system, and reseat the Port Adapter Jacket Card.

If no, check to be sure that the Port Adapter Jacket Card is installed in a Cisco 7200 VXR router with an NPE-G1 installed. If not, remove the Port Adapter Jacket Card and install it in a Cisco 7200 VXR router with an NPE-G1. The Port Adapter Jacket Card does not work with any other network processing engine or network services engine.

Is the ENABLED LED on?

If yes, the system is operational.

If no, check to be sure that the Port Adapter Jacket Card is installed in a Cisco 7200 VXR router with an NPE-G1 installed. If not, remove the Port Adapter Jacket Card and install it in a Cisco 7200 VXR router with an NPE-G1. The Port Adapter Jacket Card does not work with any other network processing engine or network services engine.

If no, suspect the Port Adapter Jacket Card is not properly seated. Power down the system, remove the Port Adapter Jacket Card, and reseat it. If the ENABLED LED remains off, contact a service representative for instructions.

Troubleshooting the Port Adapters or Service Adapters

Check the following to help isolate a problem with the port adapters or service adapters:

Are all adapter ENABLED LEDs on? If yes, the system is operational.

Are any adapter ENABLED LEDs off?

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.
