In a global retail rollout, IT teams deploy the Cisco3825-DC-3825 w/DC PWR, 2GE, 1SFP, 2NME, 4HWIC, IP Base, 128F/512D as the sole router at hundreds of remote branches. Leveraging its DC-power capability and redundant WAN links (2 GE + 1 SFP), each site establishes resilient IPsec VPN tunnels to headquarters. Outcome: 99.99% branch-office uptime, simplified centralized management via Cisco Prime, and hardware-accelerated encryption for secure, high-performance transactions.
A mid-sized cloud service provider integrates the Cisco3825-DC-3825 as its edge router to terminate BGP sessions from multiple upstream carriers. With two NME and four HWIC slots, engineers install firewall, WAN-optimization and SSL-offload modules, while the DC-power design ensures seamless integration into the data hall. Benefit: scalable throughput, end-to-end QoS enforcement, dynamic routing (OSPF/BGP) and service chaining—all in a single IP Base chassis that reduces footprint and total cost of ownership.
An energy utility substation leverages the DC-powered Cisco3825-DC-3825 to aggregate telemetry from RTUs and smart sensors over serial and Ethernet interfaces (4 HWIC ports). The 1 SFP port connects into a fiber-ring SCADA network, while AES-256 VPN tunnels secure real-time data to the central NOC. Result: sub-50 ms latency for critical sensor data, 24/7 operation in harsh environments, and streamlined remote monitoring using the router’s IP Base feature set.
