Environment Monitoring

Overview

The Cisco AS5350 and Cisco AS5400 contain temperature sensors to detect abnormal temperature conditions during system operation. The three levels of sensor detection are as follows:

1.When the operating temperature of the system exceeds 45° C, the system reaches a warning state. A

warning message appears on the console. When the operating temperature of the system drops below 45° C, another message is displayed on the console indicating a recovery. At this level of sensor detection, there is no disruption in system operation.

2.When the operating temperature of the system continues to rise above 45° C and reaches a temperature of 60° C, the system reaches a critical state.

Cisco IOS software busys out the DFCs in the chassis and shuts down the first DFC. If the operating temperature continues to be critical after 10 minutes, Cisco IOS software shuts down another DFC.

Note DFC slot numbering starts from the system board and works up from left to right. Slot 0 is reserved for the motherboard. The DFC slots are numbered sequentially. (See Figure 6-5and Figure 6-6.)

The busyout process is repeated at 10 minute intervals until the final DFC is shut down. The console displays the slot number of the DFC and the type of DFC that was shut down.

AS5350, AS5400 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.
