Starting Up the Cisco 7206 Router Shelf

Note Although an overtemperature condition is unlikely at initial startup, the environmental monitoring functions are included in this chapter because these functions also monitor internal voltages.

Starting Up the Cisco 7206 Router Shelf

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

•The power supply LEDs (OK) should light immediately when you set the power supply switch to the ON ( ) position and remain lit during normal system operation.

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

•You should immediately hear the fans operating.

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

•The I/O controller card LEDs should light in the following sequence. If they do not light as described, proceed to the section “Troubleshooting the Processor Subsystems.”

—The I/O power OK LED lights immediately and indicates that the I/O controller card is receiving DC power from the router midplane. This LED lights during a successful router boot and remains on during normal operation of the router.

—The enabled LED lights after the I/O power OK LED and indicates that the network processor card and the I/O controller card are enabled for operation by the system; however, that the enabled LED lights does not mean that the Fast Ethernet port on the I/O controller card is functional or enabled. This LED lights during a successful router boot and remains lit during normal router operation.

—The FE enabled LED lights after the enabled LED and indicates that the Fast Ethernet port on the I/O controller card is initialized and enabled for operation by the system. This LED lights during a successful router boot and remains lit during normal router operation.

—The FE link LED lights only when the Fast Ethernet port on the I/O controller card is receiving a carrier signal from the network. (This LED remains off during normal router operation unless there is an incoming carrier signal and does not indicate startup problems.)

—The slot 1 and slot 2 LEDs light after the enabled LED and indicate which PCMCIA slot is in use.

During a successful router boot, these LEDs light and remain on if a Flash memory card is present in the slot. These LEDs also blink when either slot is being accessed by the system. These LEDs do not indicate startup problems.

•The port-adapter-enabled LEDs each light when the network processor card completes its initialization of the port adapter for operation.

The enabled LED indicates that the port adapter is receiving power and has been recognized by the network processor card; it does not indicate the state of the individual port adapter interfaces.

If an enabled LED does not light, proceed to the section “Troubleshooting the Port Adapters,” later in this chapter.

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.
