How to Install Dell Intel SFP28 Module

• Verify that your device supports 25GBase-SR SFP28 transceivers and that the Dell Intel SFP28 Module is compatible with your hardware platform. Check vendor documentation or product compatibility lists for the exact model.
• If your equipment requires hot-swapping, follow your device’s guidelines for live swaps. If a maintenance window is preferred, power down the system according to your data center’s procedures.
• Gently remove any existing transceiver from the SFP28 slot, taking care not to bend or misalign connectors.
• Inspect the SFP28 slot and ensure the fiber connectors (LC) and cables are clean and free of dust or debris. Cleanliness is critical for maintaining link integrity.
• Insert the Dell Intel SFP28 Module into the SFP28 slot until it seats firmly with a definite click. Do not force the module; if it does not seat, remove and reinsert to align properly.
• Connect the MMF fiber cables to the LC duplex connectors, ensuring the correct receive/transmit orientation. Use appropriate fiber grade (e.g., OM3/OM4) to achieve expected performance.
• Power on the device (if applicable) and verify the link status via the management interface, switch LED indicators, or the device’s console. Run a basic connectivity test to confirm the 25G link is active and error-free.

Frequently asked questions

• What is the Dell Intel SFP28 Module used for? It is a plug-in optical transceiver that enables 25 Gigabit Ethernet links over multi-mode fiber, ideal for high-speed server, storage, and switch interconnections within data centers and enterprise networks.
