How to install AXIS T8643 PoE+ over Coax Compact

• Plan and assess. Before installation, evaluate the existing coax segment, camera power needs, and network topology. Confirm that the coax run length and cable quality align with the expected PoE+ performance for Axis cameras.
• Power down and prepare. Power down equipment as required and identify the best mounting location for the T8643. Choose a secure mounting spot near the camera or network access point to minimize cable runs and maintain clean installations.
• Connect coax and network. Attach the coax feed from the existing run to the T8643’s coax input, and connect the Ethernet/Data path to the appropriate camera or network switch according to Axis configuration guidelines. Ensure all connections are snug and compliant with local electrical codes.
• Power on and configure. Restore power and use Axis discovery tools to identify the T8643 unit. Configure PoE+ settings, verify camera recognition, and adjust power budgets to optimize performance for the specific Axis camera model in use.
• Verify operation and document. Test live video from the Axis camera, confirm consistent PoE delivery, and monitor the device through Axis management software. Document settings for future maintenance and calibration.
