How to install TL-SG3428MP

• Plan your network layout by mapping out device locations, PoE needs, and uplink connectivity to the core network. Ensure you have appropriate rack space and power capacity for the switch and attached devices.
• Mount the TL-SG3428MP in a standard 19-inch rack, secure it, and ensure adequate ventilation for cooling. Connect the power cord and power it on, confirming the unit boots normally before connecting devices.
• Connect PoE devices (cameras, IP phones, wireless APs) to the 24 PoE+ ports. Use appropriate CAT5e/CAT6 cables for reliable PoE delivery and data transmission. Attach the non-PoE uplink ports to your network core if needed, using the 4 uplink ports to reach fiber or higher-speed links.
• Access the management interface (web GUI or CLI) and perform initial configuration. Set a secure management IP address, define VLANs for segmentation, and configure QoS rules to prioritize business-critical traffic such as voice and cameras. Customize security settings, including 802.1X authentication, MAC address filtering, and access control lists as required.
• Update firmware to the latest stable version from TP-Link’s support site and back up the configuration after you confirm that all features are functioning as intended. Create a baseline monitoring plan to track port status, traffic levels, PoE utilization, and alert thresholds to maintain network health over time.
