C931-4P Overview C931-4P is the Cisco 931 Gigabit Ethernet security router with internal power supply. Cisco 900 Series ISRs deliver integrated security and threat defense, protecting networks from both known and new Internet vulnerabilities and attacks. These powerful, fixed-configuration routers provide secure broadband and Metro Ethernet connectivity. Service providers offering managed Ethernet WAN services can deploy them in customer locations as CPE. Centralized and remote management capabilities are available through web-based tools and Cisco IOS Software for full visibility and control of network configurations at the remote site. The 900 Series ISRs simplify the deployment of Ethernet WAN services, with end-to-end Operations, Administration, and Maintenance (OAM), Service-Level Agreement (SLA) monitoring and verification, and configuration management. This series ISRs come with a 4-port managed switch, providing LAN ports to connect multiple devices.
