How to install Cisco Catalyst 3650-48F Layer 3 Switch

Installing the Catalyst 3650-48F is a straightforward process designed to minimize downtime while maximizing performance and reliability. Follow these best-practice steps to bring your new switch online efficiently:

• Plan and prepare: Confirm rack space, power availability, and network topology. Verify that you have the appropriate stacking cables and console access ready for initial configuration.
• Rack and connect hardware: Mount the switch in a stable rack, connect power cords to a reliable power source, and install stacking cables if you intend to operate a stack. Ensure proper airflow and clearance for cooling.
• Initial console access: Connect to the console port using a suitable terminal emulator, power up the device, and access the CLI for initial basic configuration. Establish a secure management IP on the VLAN you will use for out-of-band access.
• Set up basic network parameters: Configure a hostname, management interface, and DNS settings. Create VLANs as needed and configure SVI interfaces for inter-VLAN routing if required for your design.
• Enable Layer 3 routing and policies: Activate the desired routing protocols (static or dynamic such as OSPF/EIGRP), configure routing tables, and apply ACLs or QoS policies to satisfy your security and performance requirements.
• Secure management and access: Implement 802.1X authentication for endpoints, enable secure management access (SSH), and consider role-based access control to limit administrative privileges.
• Test connectivity and performance: Validate network paths between clients, access points, and core infrastructure. Verify VLAN reachability, routing behavior, and failover in a stacked configuration.
• Save and monitor: Save the running configuration to startup, and set up ongoing monitoring and logging. Consider integration with network management tools such as Cisco DNA Center for policy-driven automation and analytics.
