Chapter 5 Troubleshooting the Installation

Troubleshooting the Processor Subsystem

If the auxiliary port is not functioning properly, check the baud rate. The auxiliary port will not function at baud rates higher than 19.2k. If the baud rate on the connecting device is set higher than 19.2k, either garbled text or nothing will be displayed on the screen.

Troubleshooting the NPE-G1 or NPE-G2

The procedures in this section assume that the NPE-G1 or NPE-G2 and the router itself are in the original factory configuration, and that you have not made changes to your configuration file.

If the NPE-G1 POWER ON LED or the NPE-G2 PWR OK LED does not go on as expected, make sure the power to the router is turned off, reseat the NPE-G1 or NPE-G2 in its slot, and restart the router.

If the POWER ON LED or PWR OK LED remains off, the system detected a processor hardware failure. (The LED should be on in normal operation.) Contact an authorized service representative for instructions.

If the NPE-G1 or NPE-G2 Gigabit Ethernet media LEDs do not come on check the cable connections, clean the fiber- optic cable connectors (see “Fiber-Optic Cleaning Information” section on page 5-10), try a different GBIC module or SFP module, and check the software to be sure the optical fiber media is selected. See the “Configuring the Native Gigabit Ethernet Interfaces” section on page 4-8.

If the EN (enabled) LED does not come on when the a Gigabit Ethernet RJ-45 port is selected, try using a different cable. If the EN LED does not come on, check the software to be sure the RJ-45 media is selected. See the “Configuring the Native Gigabit Ethernet Interfaces” section on page 4-8.

If the EN LED remains off when the GBIC or SFP media are selected, the LED is functioning properly.

If any of these actions do not produce a functioning LED, contact an authorized service representative.

If the LINK LED does not come on only when any of the Gigabit Ethernet media are in use:

Check that the router is receiving power.

Check that the correct media type is selected in software. See the “Configuring the Native Gigabit Ethernet Interfaces” section on page 4-8.

Check that the media cables are functioning and are completely connected to the NPE-G1 or NPE-G2.

If GBIC modules are being used, check to be sure they are connected to the NPE-G1.

If SFP modules are being used, check to be sure they are connected to the NPE-G2.

If any of these actions do not produce a functioning LED, contact an authorized service representative.

If the SLOT ACTIVE LED or the CF ACTV LED on the NPE-G2 does not comes on when the CompactFlash Disk slot is being used, try inserting a different CompactFlash Disk. If the SLOT ACTIVE LED or the CF ACTV LED still does not come on, contact an authorized service representative.

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.
