Replacing the Boot ROM

Step 7 Gently extract the old ROM with a PLCC-type ROM extraction tool and set the old boot ROM on a nonconducting surface. Do not use excessive force because the socket might break. (See Figure A-4.)

Step 8 Insert the new boot ROM into the socket.

Caution The notch in the ROM must align with the notch in the socket on the system board. If the ROM is installed backwards, damage will occur when the gateway is powered on.

Step 9 Replace the carrier card. (See the AS5350 Universal Gateway Card Installation Guide for instructions on installing the carrier card. This document is available on the World Wide Web and the documentation CD-ROM that comes with your gateway. See the “Obtaining Documentation” section on page xiii.)

Step 10 Replace the gateway chassis cover. (See the instructions in the “Replacing the Chassis Cover” section on page A12.)

Step 11 Power on the universal gateway. If error messages relating to memory are displayed, remove the new boot ROM and reinstall it, taking care to seat the ROM firmly in its socket.

AS5350 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.
