continuously.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Power cable not fully seated at source.

Turn the switch to the off position and

 

 

 

 

 

 

 

reseat the power cable at the power source.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

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.

SCE 2000 4xGBE specifications

The Cisco Systems SCE 2000 4xGBE is a robust solution designed to optimize IP networks and enhance service delivery. As a member of Cisco's Service Control Engine (SCE) product line, this device is particularly suited for service providers looking to manage network traffic, improve service quality, and provide a suite of advanced management features.

One of the standout features of the SCE 2000 is its ability to process and analyze network traffic in real-time. This capability allows operators to gain insights into user behavior, application usage, and overall network performance. By utilizing deep packet inspection technology, the SCE 2000 can identify different types of traffic, enabling network managers to enforce policies and prioritize critical applications effectively.

In terms of interface capabilities, the SCE 2000 offers four 1 Gigabit Ethernet (GbE) ports. This versatility allows for easy integration into existing network infrastructure while ensuring ample bandwidth for data transfer. The device supports both IPv4 and IPv6 protocols, making it future-proof and suitable for evolving network demands.

One of the significant technologies employed by the SCE 2000 is Service Level Agreement (SLA) management. This feature ensures that service providers can meet their commitments to customers by monitoring performance metrics such as latency, jitter, and packet loss. The ability to generate reports based on SLA compliance allows for better customer engagement and transparency.

Additionally, the SCE 2000 facilitates dynamic resource allocation, enabling service providers to adapt network resources based on current demand. This elasticity is crucial in managing peak loads and ensuring a seamless user experience. Furthermore, the device’s support for Quality of Service (QoS) policies ensures that critical applications receive the necessary bandwidth and resources dedicated to maintaining operational efficiency.

The SCE 2000 also emphasizes security with features such as intrusion detection and prevention capabilities, helping protect the integrity of the network. This combination of performance monitoring, traffic management, and security makes the SCE 2000 an invaluable tool for service providers.

In conclusion, the Cisco Systems SCE 2000 4xGBE is a powerful network management solution that excels in providing real-time traffic management, SLA compliance, and security features. Its capabilities make it an essential component for service providers aiming to optimize their networks while delivering high-quality services to their customers.
