how to install Cisco 4351 Router

Before you install, plan your site layout, ensure power and network readiness, and have your license keys ready. The Cisco 4351 supports a range of WAN interfaces and security features, and proper cabling, labeling, and rack placement help ensure a smooth deployment. Below is a concise setup guide to help you get started and maximize the value of your new ISR platform.

• Unbox and verify hardware: Confirm model, serials, and included accessories. Inspect for any transit damage and gather mounting hardware if you plan to rack-mount the device in a compliant enclosure.
• Connect power, network interfaces, and management access: Attach the power supply(s), wire primary and backup WAN links as required, and establish console or management access using a secure administrator account.
• Boot and initial configuration: Power on, access the console, and perform the initial bootstrap. Load the appropriate IOS XE image and license for services you intend to run—routing, firewall, VPN, and additional security or performance features as needed.
• Configure core services: Set up routing (static or dynamic), define VPN peers, enable firewall policies, and configure QoS for critical applications. If you use Cisco DNA, cloud management, or telemetry, enroll the device accordingly to enable centralized control and visibility.
• Test, verify, and monitor: Validate reachability, review logs, and confirm policy enforcement. Run end-to-end tests for essential applications, then enable ongoing telemetry and monitoring to maintain performance and security over time.
