how to install Mellanox QSFP28 Module

• Power down the host equipment if required by your network architecture, or verify hot-swappable compatibility with your switch or router prior to installation.
• Identify the correct port slot that supports a QSFP28 transceiver and ensure the slot is free of debris or obstruction.
• Remove the protective cap from the MPO/MTP connector end and inspect the connector for cleanliness; if needed, clean using proper fiber cleaning methods.
• Align the Mellanox QSFP28 Module with the slot, ensuring the module orientation matches the guide rails and the connector end aligns with the port opening.
• Gently push the module straight into the slot until it seats fully and the latches engage with a secure click. Verify that the port LED indicates link activity or a steady link state as applicable.
• Connect the MPO/MTP fiber harness to the module according to your network design. Ensure fibers are properly terminated and color-coded to avoid misplugging.
• Power on the device (if powered down) and perform a link test to confirm proper operation, speed negotiation, and lane alignment. Check for any diagnostic alerts or alarms in the switch interface.
• Document the installation in your change management system and monitor the port over the next 24–48 hours to verify stability and expected throughput.
• If you encounter issues, reseat the module, inspect optical connectors, verify fiber integrity, and consult your switch’s compatibility matrix for supported transceivers and firmware requirements.

Frequently asked questions

• What is a Mellanox QSFP28 Module? It is a high-density transceiver designed for 100GBase-X Ethernet, using the QSFP28 form factor and an MPO/MTP optical interface to deliver multi-lane 100 Gbps connectivity in data centers and enterprise networks.
• Which environments is it best suited for? The module excels in data centers, hyperscale fabrics, storage networks, and high-performance computing interconnects where space, power efficiency, and high throughput are critical.
• Does this module support hot-swapping? Yes, QSFP28 transceivers are typically hot-swappable, allowing replacements or upgrades without powering down the entire switch or chassis, depending on the switch model and policies.
• What fiber types and wavelengths are supported? Module variants cover both multimode (SR4, typically 850 nm) for short-reach links and single-mode (LR4 or similar at 1310/1550 nm) for longer distances; exact options depend on the specific transceiver variant you purchase.
• Can I monitor the module’s health and diagnostics? Many Mellanox QSFP28 modules include Digital Diagnostics Monitoring (DDM/DOM), providing real-time data such as temperature, optical power, voltage, and bias current to help with proactive maintenance.
• Is compatibility guaranteed with all switches? Interoperability is strong with major vendors, but always verify the vendor’s compatibility matrix for your exact switch model and firmware level to ensure full support and optimal performance.
• How do I verify performance after installation? Run link tests, confirm negotiated speed (100 Gbps), check error rates, and monitor the port’s diagnostic readings to ensure stable operation under load.
