LEDs

The following LEDs are used to monitor the functioning of the power supply units:

On the power supply unit (both AC-input and DC-input):

IN LED (green)

OK LED (green)

On the Front Panel (on page 2-3):

Power LED: There are two Power LEDs on the front panel (Power A and Power B), one LED corresponding to each power supply unit

On both the AC-input and DC-input power supplies, the IN LED is used to monitor the voltages received by the platform from the power source. If the input voltages are within normal operating ranges, the green IN LED is illuminated. If the input voltages are above or below normal ranges, the IN LED is not illuminated.

On both the AC-input and DC-input power supplies, the OK LED is used to monitor the power supply DC output voltages used to power the platform. The normal operating ranges for the 12 VDC output voltage is between 11.9V and 12.1V. If the output voltages are within normal operating ranges, the green OK LED is illuminated. If the 12 VDC output voltages are above (more than 12.1V) or below (less than 11.9V) normal ranges, the OK LED is not illuminated.

The Power A and Power B LEDs on the front panel indicate whether the corresponding power supply unit is functioning normally.

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.
