How to install Cisco Catalyst 9300 24-Port PoE+, Network Advantage

Install and configure the Catalyst 9300 24-Port PoE+ to maximize performance, security, and ease of management across your campus network.

• Plan your topology and power requirements before installation. Determine the placement in a standard 19-inch rack, confirm available space for proper airflow, and verify that your power supply configuration meets the PoE needs of connected devices.
• Mount the switch in a rack and connect it to a stable power source. If using redundant power, install and connect both power supplies to separate circuits to ensure continuous operation during a failure.
• Connect uplinks to your core network using suitable fiber or copper cables. Ensure the uplink bandwidth aligns with your expected traffic patterns and that your core can handle distributed workloads from the edge.
• Initial access and basic configuration: connect via console or a management interface, set administrator credentials, enable SSH, and apply the recommended IOS XE image version for Network Advantage. Establish basic network settings such as VLANs, trunking, and routing protocols as required for your environment.
• Configure PoE settings and device power policies: assign PoE port policies, set device power budgets, and monitor power usage to avoid over-subscription. This ensures all PoE devices, from IP phones to cameras, receive reliable power without impacting network stability.
• Enforce security and segmentation: implement 802.1X authentication, posture checks, and, if needed, TrustSec policies to segment traffic by device type, department, or security posture. Enable MACsec on relevant ports or paths to protect sensitive communications.
• Enable management and monitoring tools: integrate with Cisco DNA Center or your preferred management stack, configure SNMP and NetFlow/IPFIX for visibility, and set up alerts for power events, port status, and security events. Schedule firmware updates and establish a routine for patch management to maintain security commitments.
• Test and validate performance: verify end-to-end connectivity across VLANs, confirm QoS settings for voice and video, and simulate failover scenarios to ensure continuity in a real-world deployment. Document the configuration for future audits and troubleshooting.
