CISCO2851-AC-IP Use Case
Branch Office Unified Communications Gateway Deployment
Scenario: A distributed financial-services branch with 50+ IP phones and HD video endpoints leverages the CISCO2851-AC-IP-2851’s integrated AC+PoE to power endpoints, 3 PVDM DSP modules for voice processing, and 4 HWIC slots for analog-failover modules. The dual-Gigabit Ethernet interfaces and Cisco IOS IP Base enable end-to-end QoS and unified voice, video, and data convergence on a single platform. Outcome: 30% reduction in infrastructure costs, 99.9% call uptime, and simplified network management through centralized configuration and monitoring.
Multi-Site Secure VPN and WAN Resiliency for Retail Chains
Scenario: A national retail chain deploys the CISCO2851-AC-IP-2851 at 200 stores to establish secure MPLS and Internet VPN tunnels over dual-GE links. Two AIM modules provide stateful firewall and intrusion prevention, while SFP ports deliver link diversity and failover. Outcome: Achieved PCI-DSS compliance, 40% reduction in network downtime, centralized security policy enforcement, and improved POS transaction throughput.
Industrial IoT Edge Gateway for Smart Manufacturing
Scenario: An automotive manufacturing plant uses the CISCO2851-AC-IP-2851 as an IoT edge gateway aggregating sensor and PLC data via 4 HWIC serial modules and high-density NME-XD flash for local analytics. AC+PoE powers industrial cameras and wireless APs; dual AIM modules secure SCADA traffic with real-time IPS. Outcome: 25% decrease in production-line interruptions, enhanced operational visibility, and streamlined remote firmware updates over secure VPN.
