How to install HPE QSFP-DD Module
- Prepare the equipment: Ensure you are working in a static‑free environment and that the host device supports QSFP‑DD modules and 400GBASE‑FR4 optics.
- Power and safety: If your system requires power down, follow your device’s standard power‑down procedure. Many modern systems support hot‑swap for QSFP‑DD modules; confirm hot‑plug capability for your chassis and slot.
- Remove packaging: Carefully remove the QSFP‑DD module from its protective packaging, handling it by the edges to prevent contamination of the optical surfaces.
- Insert the module: Align the module with the QSFP‑DD slot, ensuring the connector engages straight. Gently press until the retention latch snaps into place, signaling a secure connection.
- Connect fiber cabling: Attach SMF cables to the LC connectors on the module, observing proper bend radii and avoiding excessive tension. Label and route fibers to minimize crossovers and maintain clean, organized cabling.
- Verify operation: Power up (if required) and check the host device’s management interface for link status, lane health, and 400G link establishment. Use built‑in diagnostics to monitor optical power and temperature for reliable operation and proactive maintenance.
