Power Supply Safety Features (Enhanced AC-Input Power Shelf)

The power supplies in the enhanced AC-input power shelf have the following safety features:

AC power supplies installed in the enhanced AC-input power shelf are protected against overcurrent by circuit breakers, and against overtemperature by internal protection circuits.

A metal spring-clip locking mechanism in the ejector levers holds individual AC power supplies in place and prevents the power supply from vibrating or sliding out of the power bay and dislodging from the power backplane.

Double grounding lugs (as per NEBS requirements) on both the enhanced AC-input power shelf and the dial shelf provide electrical grounding.

A metal safety cover slides into grooves on the rear underside of the dial shelf to shield the DC power cables from possible short circuit and to protect from electrical shock.

The power supplies are self-monitoring. Each power supply monitors its own temperature and internal voltages. An internal fan in each power supply draws cooling air from the front of the power shelf, through the power supply, and out the rear of the power shelf. The power supply airflow is separate from that of the rest of the Cisco AS5800 Universal Access Server components.

Internal monitoring data is passed to the dial shelf through the maintenance bus (MBus) monitoring system. You can view this data through a terminal connected to the router shelf console port. The command to display the monitoring information is described in the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (DOC-AS5800-SICG=). The Cisco AS5800 Universal Access Server Software Installation and Configuration Guide will be replaced by the Cisco AS5800 Universal Access Server Operation, Administration, Maintenance, and Provisioning Guide, available later this year.

AS5800 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
