Installing the Dial Shelf in the Rack

One person can not install the dial shelf chassis in the rack unassisted. Two or preferably three people will be needed.

To secure the rack-mount brackets to the posts or mounting strips in the rack, you must use the slotted mounting screws provided. Because the brackets support the entire weight of the chassis, be sure to use at least two slotted screws per bracket.

Be sure you have the dial shelf prepped as described in the previous chapter before installing it in the rack. To install the dial shelf chassis in the rack, complete the following steps:

Tips To prevent injury, review the safety precautions in the “Safety Recommendations” section on page 2-14before installing the dial shelf in the rack.

Step 1 Verify that your path to the rack is unobstructed and ensure that the rack is stabilized.

Step 2 Attach one support bracket to each front post or mounting strip using the provided slotted screws and a 1/4-in., flat-blade screwdriver. Ensure that the support brackets are level. (See Figure 3-5and Figure 3-7.)

Note Because the brackets support the weight of the entire chassis, be sure to use at least two slotted screws per bracket. These brackets also ensure that the required space between the dial shelf and the power supply is available.

Step 3 Position the dial shelf chassis in front of the rack.

Warning Two people are required to lift the chassis. Use the handles on the chassis sides. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies, the filter module, or on the blower assembly. These handles are not designed to support the weight of the chassis. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

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.
