  • Cisco 5921 Embedded Services Router Data Sheet
    Data Sheet Cisco 5921 Embedded Services Router The Cisco ® 5921 Embedded Services Router (ESR) is a Cisco IOS software router application. It is designed to operate on small, low-power, Linux-based platforms to extend the use of Cisco IOS ® Software into extremely mobile and portable communications systems. You can use the Cisco 5921 ESR in a variety of applications. The Cisco 5921 ESR is part of the Cisco 5900 Series ESRs, all optimized for mobile and embedded networks that require IP routing and services. The flexible, compact form factor of the Cisco 5900 routers, complemented by Cisco IOS Software and Cisco Mobile Ready Net capabilities, provides highly secure data, voice, and video communications to stationary and mobile network nodes across wired and wireless links. Low-Cost Vehicle Communications Systems The Cisco 5921 ESR complements the Cisco 5915 and 5940 ESR hardware routers, providing integrators with a cost-effective solution for addressing smaller, highly-integrated applications. The Cisco 5921 ESR can be combined with system-specific applications onto a single, small, low-power hardware solution. Portable Communications Devices By not restricting the product developer to a specified form factor, the Cisco 5921 ESR offers integrators creative flexibility to design hardware to meet unique market requirements. The router targets low-power systems, making it ideal for use in portable, battery-powered devices. Sensors The Cisco 5921 ESR’s network optimization capabilities support the development of security-protected sensors deployed in self-forming, self-healing, infrastructure-less networks. It provides immediate connection with no pre- configuration of peers required; no need for connectivity to a centralized network; and reach beyond the range of a fixed network.
