How to install Accortec QSFP+ Module

• Prepare the system: Power down or ensure you have a safe maintenance window for your networking equipment. This reduces the risk of ESD or misalignment during installation.
• Inspect the connector: Verify the QSFP+ port on both ends is clean and free of debris. Check that the DAC cable length matches your rack layout and avoids sharp bends.
• Insert with care: Align the Accortec QSFP+ Module into the QSFP+ port until it is fully seated and the latch engages securely. Do not force the module; ensure a smooth, even connection.
• Connect the DAC cable: Attach the Direct Attach Copper (DAC) twinax cable to the module and the corresponding port on the adjacent switch, router, or server. Ensure the connectors are fully seated for reliable signal transmission.
• Power and test: Restore power and monitor link status indicators on the connected devices. Confirm that all ports show active links and verify throughput with a basic performance test and appropriate network management tooling.
