Chapter 9 Removal and Replacement Procedures

Removing and Replacing the Power Supply

Installing an AC-Input Power Supply

Warning This product requires short-circuit (over current) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations.

Step 1 Ensure that the system (earth) ground connection has been made. For ground connection instructions, see Connecting the System Ground, page 4-16

Step 2 Verify that the power switch is in the Off (0) position.

Step 3 Grasp both power supply handles, as shown in Figure 9-2. Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay.

Step 4 Securely tighten the power supply captive installation screws. (See Figure 9-1.)

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

Step 5 Plug the power cord into the power supply.

Step 6 Connect the other end of the power cord to an AC-input power source.

Caution In a system with dual power supplies, connect each power supply to a separate input source. In case of a power source failure, the second source will most likely still be available.

Step 7 Turn the switch on the power supply to the On () position.

Step 8 Verify power supply operation by checking the power supply LEDs.

The power supply LEDs should be in the following states:

INPUT OK LED is green

FAN OK LED is green

OUTPUT FAIL LED is not lit

If the LEDs indicate a power problem, see Identifying Startup Problems, page 8-6for troubleshooting information.

Removing a DC-Input Power Supply

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.

Warning Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock, keep hands and fingers out of the power supply bays and backplane areas.

Step 1 Verify that power is off to the DC circuit connected to the DC-input power supply you are removing.

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.
