How to Install Eaton Tripp Lite Series Cisco-Compatible QSFP-40G-LR4 QSFP+ Transceiver

• 1) Verify compatibility: Confirm your Cisco switch or router supports QSFP+ LR4 modules and that your fiber optic cabling is single-mode with LC connectors. Check device documentation for approved transceiver lists to avoid compatibility issues.
• 2) Prepare fiber and cleanliness: Inspect and clean LC connectors before installation. Ensure fiber cables are routed with proper bend radii and low tension to protect connector ends and maintain link integrity.
• 3) Power considerations: If your equipment supports hot-swapping, you can insert the transceiver with the system powered on. If your environment requires power-down procedures, follow your device’s maintenance guidelines to minimize disruption.
• 4) Insert the transceiver: Gently align the QSFP+ module with the port and slide it into place until it clicks securely. Confirm that any status LEDs indicate a healthy device presence and link state per your hardware’s indicators.
• 5) Connect the fiber: Attach the single-mode LC fiber pair to the module, ensuring correct transmit and receive orientation. Use labeled, quality cables to minimize cross-talk and insertion loss.
• 6) Verify operation: On your Cisco device, verify the interface status and 40G link using appropriate show commands. Check the lane status, errors, and optical budget to ensure the link is stable and within specification.
