Replacing Flash Memory SIMMs

Appendix

Step 8 Insert the new SDRAM DIMM by sliding the end with the metal fingers into the DIMM socket, as shown in Figure A-6.

Step 9	Snap the latches into place. Do not use excessive force because the socket might break.
Step 10	Replace the gateway chassis cover. (See 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 SDRAM
	DIMM and reinstall it, taking care to seat the DIMM firmly in its socket.

The system board contains three sockets for 5V Flash memory SIMMs (see Figure A-3):

•The first two Flash memory sockets hold SIMMs containing the Cisco IOS software image. Cisco recommends that you install the first SIMM into the first Flash memory socket. (Socket 0 in Figure A-3.) For future expansion, install the second SIMM in the second Flash memory socket. The SIMMs are 32 MB, and the capacity of both SIMMs must match.

–For system memory, the total capacity is 64 MB (two, 32 MB SIMMs).

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.
