How to Install Ortronics Check QSFP28 Module

Installing the Ortronics Check QSFP28 Module is designed to be straightforward and safe, minimizing downtime and ensuring proper optical performance. Follow these best-practice steps to achieve a reliable uplink quickly.

• Power down the equipment or place it in a maintenance window to prevent electrostatic discharge and to protect the optical interfaces during handling.
• Inspect the QSFP28 port and the MPO/MTP fiber assembly for any signs of damage, dust, or contamination. Clean connectors as recommended by your data-center procedures.
• Align the Ortronics Check QSFP28 Module with the corresponding QSFP28 port, and gently insert until the module seats securely and the locking mechanism engages.
• Route the MPO/MTP fiber ribbon carefully to minimize bending and ensure proper strain relief. Connect the fiber to the module according to your network design, avoiding sharp bends or excessive slack.
• Power up the device and verify link status via the switch/router management interface. Confirm that the 100G link is established, check the port speed, and run a basic throughput test to validate performance.
• If interworking issues arise, consult your OEM device documentation for any required port default settings, and ensure the transceiver is selected as the active module in the device’s port configuration.
