How to install Extreme Networks 40G PSM4 QSFP+ MPO 10km

• Power down or verify hot-swap readiness for the port you are upgrading, and ensure you follow your data-center’s ESD and safety procedures.
• Remove any protective covers from the QSFP+ port and the MPO/MTP fiber harness, and verify that you have the correct fiber harness for 4 parallel lanes.
• Insert the Extreme Networks 40G PSM4 QSFP+ module firmly into the QSFP+ port until the latch engages and the module is securely seated.
• Connect the MPO/MTP fiber harness to the module’s MPO interface, ensuring correct lane mapping and maintaining proper polarity as required by your network design.
• Route fiber with appropriate bend radius and cable management, then connect the other end to the corresponding device or cabling infrastructure.
• Power up the equipment and verify link status, performing basic diagnostics or loopback tests as recommended by your network management tools to confirm that all four lanes are active and aligned for 40 Gbps traffic.
• Document the installation, including port numbers, fiber harness IDs, and distance, to support ongoing maintenance and future scalability.
