Chapter 9 Removal and Replacement Procedures

Removing and Replacing the Power Supply

Step 2 Remove the plastic bag attached to the front panel and put aside. This bag contains two plastic terminal block barriers, two cable ties, and two cable holder covers.

Step 3 Verify that power is off to the DC circuit connected to the power supply you are installing. Grasp both power supply handles, as shown in Figure 9-4. Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay.

Step 4 Tighten the power supply captive installation screws.

Warning Power supply captive installation screws must be tight to ensure protective grounding continuity.

Note As the power requirement of the SCE8000 will not exceed 1350W, it is not necessary to connect two pairs of input wires to each power supply. Should it be desired to connect two pairs of input wires, both pairs of input wires for one 2700W DC-input power supply must come from the same battery system (A feed); and both pairs of input wires for the other power supply must come from another battery system (B feed).

Note For multiple DC input power supply, each DC input must be protected by dedicated circuit breaker or fuse. The circuit breaker or fuse should be sized according to the power supply input rating and local or national electrical code requirements.

Step 5 Remove the four screws securing the terminal block cover, and slide the cover off of the terminal block.

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.
