How to install Cisco 10/25GBASE-LR SFP28 Module for SMF

Installing this transceiver is a straightforward process aligned with standard SFP28 procedures. Follow these steps to ensure proper seating, alignment, and link establishment without disrupting integrated networks:

• Prepare the hardware: Power down or follow your organization’s hot-swap procedure for the device slot if required, and verify there are no outstanding maintenance tasks in progress.
• Insert the module: Align the SFP28 module with the slot and firmly insert it until it clicks into place. Do not force the module or apply lateral pressure to connectors.
• Connect fiber cabling: Attach a corresponding LC duplex fiber pair to the module, ensuring correct polarity and clean fiber ends. Lightly secure the fiber to avoid unnecessary strain on the connector.
• Power up and verify: Re-energize the device and check link status via the management interface or front-panel LEDs. Confirm that the port negotiates to the desired speed (10G or 25G) and that the link is up on the correct remote end.
• Enable diagnostics and monitoring: If applicable, enable Digital Diagnostics Monitoring (DDM) and verify optical power levels, temperature, and other health indicators through the supplier’s or device’s management tooling.
