how to install Eaton Tripp Lite Series Cisco-Compatible QSFP-40G-SR4 QSFP+ Transceiver

• Power down and unplug the equipment before installation to prevent ESD and hardware damage; follow your equipment’s safety guidelines and static precautions.
• Insert the QSFP+ transceiver into an available QSFP+ port until it seats securely in the receptacle, ensuring proper alignment and a firm click or seating indication from the chassis.
• Connect a multimode fiber patch cable with an MTP/MPO connector to the transceiver, selecting the correct OM3/OM4 fiber type and verifying fiber polarity and cleanliness to minimize insertion loss.
• Power on the device and verify the link status through the switch or router management interface; check for optical activity, link lights, and appropriate port speed negotiation.
• If needed, update the device firmware or software to ensure compatibility with 40GBASE-SR4 modules and monitor performance using built-in diagnostics and error counters; handle the module by the edges and store it in an anti-static environment when not in use.
