Appendix C Installing and Upgrading Memory and Packet Voice Data Modules

Installing a SIMM

Step 4 Press the DIMM firmly into the slot until the slot guides on each side of the slot move up and over the end of the DIMM. If the guides do not move up over the edge of the DIMM, move them with your hands.

Installing a SIMM

You can install one SIMM to increase the amount of Flash memory in the router. The SIMM used to upgrade Flash memory is 16 MB in size.

Follow these steps to install a SIMM on the router motherboard.

Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the router. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.

Step 1 Locate the SIMM slot on the motherboard. See Figure C-3 on page C-4.

Step 2 Remove any existing SIMM by pulling the locking spring clips on both sides outward and tilting the SIMM free of the clips.

Step 3 Face the front panel of the router. Hold the SIMM with the component side toward you.

Caution Handle SIMMs by the card edges only. SIMMs are ESD-sensitive components and can be damaged by mishandling.

Step 4 Position the SIMM so that the indexing slot in the connector (bottom edge) of the SIMM is lined up with the indexing tab inside the SIMM slot. Tilt the SIMM

45degrees toward the rear of the router, and insert it into the slot (see Figure C-5). Rock it into its vertical position, using the minimum force necessary. When the SIMM is properly seated, the connector springs will click into place.

1760 specifications

The Cisco Systems 1760 series routers are part of Cisco’s popular line of integrated services routers, designed primarily for small to medium-sized businesses and branch offices. The 1760 series was introduced to provide robust connectivity and routing solutions that facilitate secure and reliable networking. Aimed at offering flexibility, these routers integrate multiple functionalities to enhance operational performance.

One of the main features of the Cisco 1760 router is its modularity. It supports various interface and service modules that allow for customization based on specific networking needs. This modular design enables businesses to expand their networking capabilities over time without necessitating a complete hardware overhaul. The router typically comes equipped with two WAN slots and numerous interface options, including Fast Ethernet and serial interfaces.

The 1760 series routers also support advanced security features, providing businesses with a secure environment for their data transmissions. Built-in firewall capabilities, along with support for Virtual Private Network (VPN) protocols, ensure that sensitive information remains protected. Furthermore, the integration of IPsec and MPLS security features assists organizations in maintaining secure and scalable connections across diverse networks.

Another characteristic of the Cisco 1760 is its support for various technologies, including Quality of Service (QoS). QoS functionality allows network administrators to prioritize traffic, ensuring that critical applications receive the bandwidth they require while minimizing latency. This ability is particularly valuable in environments where voice, video, and essential data applications compete for resources.

The router’s ease of management is also noteworthy. With Cisco’s IOS (Internetwork Operating System), the 1760 provides a user-friendly interface allowing for straightforward configuration and monitoring. The simplicity in managing the network devices helps reduce the burden on IT personnel and enhances overall operational efficiency.

Further enhancing the router’s capabilities is its support for voice over IP (VoIP) applications, making it an ideal choice for organizations looking to implement modern telephony solutions. The ability to support multiple voice channels while maintaining adequate data throughput positions the 1760 as an attractive option for businesses transitioning to unified communications.

In summary, the Cisco Systems 1760 series routers exhibit a harmonious blend of modularity, robust security, traffic management, and VoIP support. They effectively meet the demands of modern networking environments, making them a reliable choice for organizations aiming to streamline operations while ensuring secure connectivity. With their adaptable design, these routers can serve as a powerful backbone for enterprise networking needs.
