how to install Extreme Networks QSFP+ Module

Installing the Extreme Networks QSFP+ Module is designed to be straightforward in compatible environments. Follow these steps to ensure proper seating, connection, and operation while preserving link integrity and reducing the risk of damage to the port or fiber jig.

• Prepare the workspace by ensuring you are grounded and free of static discharge. Confirm you have the correct port on your Extreme Networks device and that fiber cables are appropriate for the chosen LM4 fiber type (multi-mode or single-mode).
• Power down the equipment if required by your chassis’ hot-swap guidelines, or verify that the port supports safe hot-swapping per your device’s maintenance policy.
• Align the QSFP+ module with the port slot, keeping the connector oriented correctly. Gently insert the module into the port until it seats firmly and the retention mechanism locks in place with a click.
• Attach the fiber patch cables to the module’s LC duplex connector, ensuring the correct polarity and that both ends are secured. Use appropriate protective dust caps if the cables are not connected immediately.
• Power up the device (if you powered it down) and monitor the port status via the device management interface. Confirm that the port negotiates to 40 Gbps and that the link light indicators reflect an active connection.
• Run basic connectivity tests to verify end-to-end reach and throughput. Document port IDs, cable configurations, and any relevant performance metrics for future reference and maintenance.
