How to install Dell Networking Transceiver, 40GbE QSFP+LR4

• Prepare the work area: ensure you have clean, properly rated single-mode fiber cables, an appropriate fiber cleaning kit, and your Dell Networking switch documentation on hand.
• Verify compatibility: confirm your Dell switch model is on the qualified list for this QSFP+ LR4 transceiver to guarantee supported operation and optimal performance.
• Handle with care: hold the transceiver by its edges; avoid touching the optical connectors to prevent contamination that could degrade link quality.
• Install the module: align the QSFP+ LR4 module with the switch’s QSFP+ port, slide it in firmly until the retention mechanism latches, and ensure it is seated securely.
• Connect the fiber: remove protective cap from each LC connector, inspect fiber ends for cleanliness, and connect the four LC duplex fibers as required by your topology. Route fibers to prevent excessive bending or tension.
• Power and verify: if your network allows hot-swapping, you can install the module with power on; otherwise, power down the switch before insertion. After installation, check the port status in the switch management interface; confirm a stable 40GbE link and verify traffic flow using a quick throughput test or loopback test as appropriate.
