CISCO2811-AC-IP Use Case
Branch Office Converged Voice & Data with PoE and Modular Scalability
A regional retail office implements the CISCO2811-AC-IP-2811 w/ AC+POE, 2FE, 4HWICs, IP BASE and 2 PVDMs to power IP phones, credit-card terminals and access control devices over a single chassis. Four HWIC slots host WAN and security modules, while PoE delivers up to 15.4W per port. Benefit: unified voice/data on one router, reduced rack space and CAPEX, plus built-in QoS for crystal-clear calls and Point-of-Sale reliability.
Secure Multi-Site VPN Connectivity for Distributed Enterprises
A manufacturing firm links five satellite plants using the CISCO2811-AC-IP-2811’s 2FE ports, 1 NME slot for 3G/4G backup and IP BASE routing. Two HWIC VPN modules establish AES-256 IPSec tunnels to HQ, while 2 AIMs enforce zone-based firewall policies. Outcome: high-performance, encrypted WAN connectivity with automatic failover, centralized policy control and 99.9% uptime for ERP and SCADA traffic.
Business Continuity via Cellular Backup & Out-of-Band Management
A financial services branch deploys CISCO2811-AC-IP-2811 with a 3G/4G NME card in the network operations center for OOB access. The platform’s AC+POE powers remote security cameras, and AIM modules run secure management agents. In case of primary WAN failure, the router automatically switches to cellular, ensuring uninterrupted VPN, VoIP and monitoring. Benefit: guaranteed 24/7 connectivity, rapid incident response and minimized revenue loss.
