Introduction

The Cisco 900 Series Integrated Services Routers (ISR 900) combine WAN, comprehensive security, and advanced connectivity in a compact, fanless platform. The routers are designed to provide enterprise-class security and connectivity for small to medium businesses. The ISR 931 model comes with a 4-port managed switch, providing LAN ports to connect multiple devices and up to 250 Mbps of VPN throughput for high performance. These small, yet powerful, fixed-configuration routers provide secure broadband and Metro Ethernet connectivity. The routers deliver integrated security and threat defense, protecting networks from both known and new Internet vulnerabilities and attacks.
