Chapter 8 Troubleshooting

Troubleshooting Overview

If the Status LED is flashing orange, indicating a warning state, check the user log: At the prompt, type: more user log

If any of the following warning messages appear, and the root cause is not obvious and easily solved (such as obstruction of external air-flow) turn the Cisco SCE8000 platform off and call technical support.

"voltage problem:"

"fans problem"

"abnormal raise in interior temperature:"

Troubleshooting the Power Subsystem

Check the following to help isolate a problem in the power subsystem. In the normally configured Cisco SCE8000 platform with redundant power supply units, it is unlikely that the device will not start at all. However, at startup it should be verified that both power supply units are operational, and therefore the following steps should be followed if the Power LED on the front panel remains unlit when the Cisco SCE8000 platform is powered up.

Note If the system powers off due to an environmental shutdown, wait at least one minute before manually rebooting the system, or it will pause indefinitely.

Power source is faulty.

Turn the switch to the off position, connect the

 

 

 

power cable to another power source, if available,

 

 

 

and turn the switch back on.

 

 

 

 

Faulty power cable.

Turn the switch to the off position, remove the cable

 

 

 

and replace it.

 

 

 

 

Faulty power supply.

If the system still fails to come up when the power

 

 

 

supply is connected to a different power source with

 

 

 

a new power cable, the power supply unit is

 

 

 

probably faulty. Contact a service representative.

SCE8000 specifications

Cisco Systems SCE8000 is an advanced service control edge solution designed to enhance the management and performance of service provider networks. Targeted at carriers and large enterprises, the SCE8000 is characterized by its capacity to efficiently handle traffic management, quality of service (QoS), and policy enforcement across various services including voice, video, and data.

One of the main features of the SCE8000 is its scalability. The platform supports a high-density architecture, allowing service providers to seamlessly expand their networks to accommodate growing traffic demands. This scalability is complemented by an impressive throughput, which enables the handling of millions of concurrent sessions, making it ideal for environments with significant user activity.

The SCE8000 employs advanced traffic management capabilities, leveraging deep packet inspection (DPI) technology. This allows for granular visibility into network traffic, enabling service providers to make informed decisions about resource allocation and policy application. Additionally, the device supports multiple protocol analysis, ensuring compatibility across various network services and enhancing overall efficiency.

Quality of Service (QoS) is another critical characteristic of the SCE8000. The platform provides sophisticated mechanisms to prioritize traffic, thereby ensuring that delay-sensitive applications such as VoIP and video streaming receive the necessary bandwidth. This capability is enhanced by Cisco's intelligent traffic shaping and congestion management features, which work together to optimize the user experience even in congested network conditions.

The SCE8000 also integrates robust security features, including session initiation protocol (SIP) security, to protect against malicious attacks and maintain service integrity. This is particularly important in today's cyber landscape where service providers must safeguard their infrastructure from various threats.

Automation and programmability are essential characteristics of the SCE8000, enabling operators to implement policies quickly and efficiently. This feature allows for dynamic scaling and rapid deployment of new services, significantly reducing the time to market for new offerings.

In conclusion, Cisco Systems SCE8000 stands out as a powerful platform for managing service provider networks. With its high scalability, advanced traffic management, quality of service assurance, robust security features, and automation capabilities, the SCE8000 enables service providers to deliver a superior customer experience while optimizing their operational efficiency. This makes it an invaluable asset for any organization looking to enhance its network performance and service delivery.
