Identifying Startup Problems

•The dial shelf interconnect port adapter link status LED lights.

The link status LED indicates an active connection to the dial shelf and lights when the interconnect port adapter is receiving a carrier signal from the dial shelf controller card. This LED should light and remain on when the access server is operating.

If the interconnect port adapter link LED does not light, proceed to the section, “Troubleshooting the Dial Shelf Interconnect Port Adapter.”

•When all router shelf LEDs light to indicate that the system has booted successfully, the initial system banner should be displayed on the router shelf console screen. If it is not displayed, verify that the terminal is set correctly and is properly connected to the I/O controller card console port as described in the “Connecting to the Router Shelf Console and Auxiliary Ports” section on page 3-31.

Troubleshooting the Router Installation

Your Cisco 7206 routers went through extensive testing before leaving the factory. However, if you encounter problems starting the routers, use the information in the chapter “Troubleshooting the Installation” in the Cisco 7206 Installation and Configuration Guide (Document Number DOC-7206-ICG=) to help isolate the cause of the problems. Be sure to review the safety warnings listed in the publication Regulatory Compliance and Safety Information for the Cisco 7200 Series Routers (Part Number 78-3419-xx) that accompanied your Cisco 7206 before using troubleshooting procedures.

If you are unable to easily solve the problem, contact a customer service representative for assistance and further instructions. Be prepared to provide the representative with the following information:

•

•

•

•

•

•

Date you received the router

Chassis serial number

Type of software and release number

Brief description of the problem you are having

Brief explanation of the steps you have taken to isolate and resolve the problem

Maintenance agreement or warranty information

Figure 5-1shows the general troubleshooting strategy for Cisco 7206 routers. Refer to this chart, as necessary, to isolate problems to a specific subsystem; then resolve the problem if possible.

Starting Up the Cisco 5814 Dial Shelf

When you first power ON the dial shelf, the following should occur:

•Both PEM power LEDs should light immediately and remain on during normal system operation. If you are using the AC-input power shelf, both AC-input power supply LEDs should light.

•

•

If the green power LEDs do not light, proceed to the section “Troubleshooting the Power Subsystem.”

You should hear the fans operating in the blower assembly.

If the fans do not operate, proceed to the section “Troubleshooting the Cooling Subsystems.”

The LEDs on the dial shelf controller card, modem cards, and trunk cards should light as follows:

AS5800 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
