Troubleshooting the Processor Subsystems

•Is the FE ENABLED LED on?

—If yes, the Fast Ethernet port on the I/O controller is initialized and enabled for operation.

—If the FE enabled LED remains off at system startup, there is probably a problem with the Fast Ethernet port on the I/O controller.

Troubleshooting the Network Processor Card

These procedures assume that the I/O controller card, network processor card, and router shelf are in the original factory configuration and that you have not made changes to your configuration file.

•Is the I/O controller card enabled LED on? (This LED should light in normal operation.)

—If the I/O controller card enabled LED does not light as expected and you have checked the I/O controller card, make sure that the power to the router is OFF, reseat the network processor card in its slot, and restart the router.

—If the enabled LED remains off, the system detected a processor hardware failure. Ensure that a partially seated port adapter is not causing the system to hang. Proceed to the following section, “Troubleshooting the Port Adapters.”

Troubleshooting the Port Adapters

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

•

•

Are all port adapter enabled LEDs on?

If yes, the system is operational.

Are any port adapter enabled LEDs off?

—If the enabled LED on an individual port adapter is off, suspect that the port adapter has pulled away from the midplane. Reseat the port adapter in its slot and verify that the port adapter levers are in the locked position. (You do not have to power OFF system power when removing or replacing port adapters.) After the system reinitializes the interfaces, the enabled LED on the port adapter should light.

—If the enabled LED remains off, suspect a faulty port adapter. Replace the port adapter with a new one.

If the new port adapter enable LED fails to light, there may be a problem with the I/O controller card or the network processor card. Contact a service representative for instructions.

Troubleshooting the Dial Shelf Interconnect Port Adapter

Check the following to help isolate a problem with the interconnect port adapter:

•Is the dial shelf interconnect port adapter enabled LED on?

—If yes, the system is operational.

—If no, verify that the interconnect port adapter is seated properly and that the port adapter levers are in the locked position.

If the enabled LED remains off, reseat the port adapter and verify that the port adapter levers are in the locked position. Use the reload command to reload the system software.

—If the enabled LED remains off, see the section “Troubleshooting the Power Subsystems” to check your power connections.

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.
