The SYSTEM and PWR MGMT LEDs on the supervisor modules indicate that there could be problems with the supervisor module or any of the other device modules.

When you start up the device, the supervisor module STATUS and CMP STATUS LEDs are amber while the module runs diagnostic tests. When the module passes the diagnostic tests and becomes operational, the STATUS and CMP STATUS LEDs become green. For devices that have two supervisor modules, the ACTIVE LED is green for the active supervisor module or amber for the standby supervisor module.

When the SYSTEM and PWR MGMT LEDs are green, the device does not detect any critical system problems. Amber, red, or unlit LEDs indicate system problems that you need to resolve, possibly with other system modules.

For a listing of supervisor module LEDs and the conditions that they indicate, see Table C-2 on page C-2.

To troubleshoot for a hardware problem with the supervisor module, follow these steps until the problem is resolved:

Step 1 Check if the STATUS or CMP STATUS LED is amber, red, or unlit on each supervisor module as follows:

•If either the STATUS or CMP STATUS LED is amber or flashing red, a minor (amber) or critical (flashing red) overtemperature condition exists. Contact TAC for assistance (see the “Contacting Customer Service” section on page 7-6).

•If the STATUS LED is red, the initialization process detected a parity error condition. Contact TAC for assistance (see the “Contacting Customer Service” section on page 7-6).

Step 2 If the STATUS and CMP STATUS LEDs are unlit, check the module seating and power connections as follows:

a.Loosen the captive screws on the module so that they are no longer in contact with the chassis.

b.Unseat the module by pressing the ejector buttons on each end of the module and swinging out each ejector lever.

c.Place one hand on the handle for the module and pull the module part way out of the chassis.

d.Push the module back into the chassis until it is seated on the midplane.

e.Rotate both ejector levers until they both touch the front of the module. Make sure that each captive screw on the fan tray is aligned with its hole in the chassis.

f.Securely tighten each captive screw (to 69 N m [8 in-lbs]) to the chassis.

g.Verify that the Output LED on each power supply is lit. If the Output LED is not lit, troubleshoot the power supply unit (see the “Troubleshooting the Power Supply” section on page 7-2).

Step 3 If the PCMCIA LED is not lit, the compact flash slot is empty. If you need to load a compact flash card in the slot, make sure that the compact flash card is formatted correctly for the slot.

Step 4 Contact TAC for assistance (see the “Contacting Customer Service” section on page 7-6).

Troubleshooting the Fabric Modules

The following conditions indicate problems with one or more fabric modules:

•The FAB LED on the chassis is amber.

•The STATUS LED on the fabric module is red.

Cisco Systems 7000 series routers are pivotal in the landscape of networking, providing high-performance, reliable solutions for enterprise environments and service providers. These routers were designed to support the growing demands of digital communication, offering robust features that enhance connectivity and streamline network operations.

One of the primary characteristics of the Cisco 7000 series is its modular architecture. This allows for the integration of various interface modules and processing units, enabling organizations to customize their routers according to specific networking needs. The modularity supports scalability, as businesses can upgrade or replace components as their requirements evolve without having to replace the entire system.

The Cisco 7000 series incorporates advanced routing protocols, ensuring efficient data packet management and traffic flow. It supports multiple protocols, including OSPF, BGP, and EIGRP, facilitating seamless integration into a variety of network environments. This flexibility is essential in modern networks, where diverse communication protocols are in use.

Load balancing capabilities are another significant feature of the Cisco 7000 series. This functionality allows for the optimal distribution of network traffic across multiple paths, enhancing performance and redundancy. By ensuring that no single route is overwhelmed, organizations can maintain uptime and improve overall user experience.

Security is a top priority for many businesses, and the Cisco 7000 series addresses this need with built-in security features. It supports Virtual Private Networks (VPNs) and access control lists (ACL) to provide secure remote access and protect sensitive data from unauthorized access. This capability is vital in today’s threat landscape, where data breaches can have far-reaching consequences.

The series also boasts high throughput and low latency, making it suitable for bandwidth-intensive applications like video conferencing and cloud computing. Coupled with Quality of Service (QoS) features, the Cisco 7000 ensures that critical applications receive the bandwidth they need, thereby enhancing overall network performance.

In terms of manageability, the Cisco 7000 routers come equipped with advanced monitoring and diagnostic tools. Network administrators can easily track performance metrics and identify potential issues before they escalate, minimizing downtimes and maintaining business continuity.

In summary, the Cisco Systems 7000 series routers are a sophisticated solution for organizations seeking to optimize their networking infrastructure. With modularity, robust routing protocols, load balancing, security features, high performance, and comprehensive manageability, the Cisco 7000 series stands out as a reliable foundation for successful network operations in an increasingly connected world.
