How to install Extreme Networks QSFP+ Module

• Power down the compatible device (switch, router, or optical line card) or follow vendor guidance for hot-swappable insertion if supported.
• Ground yourself and handle the QSFP+ module by the edges to prevent damage to connectors.
• Remove any protective caps from the module and the fiber connectors, and inspect the fiber ends for cleanliness.
• Insert the QSFP+ module into the appropriate slot until it seats firmly and the latch engages. Do not force the module; if you feel resistance, verify alignment and slot compatibility.
• Reconnect fiber trunks, ensuring connectors are clean and properly mated (use appropriate LC/MPO connectors as required by your cabling plan). Avoid bending fibers sharply and maintain correct bend radii.
• Power up the device and monitor the status LEDs and management console for a healthy link. Run basic connectivity tests and verify throughput to confirm proper operation.

Frequently asked questions

• Q: What is a QSFP+ LR4 module and what is it used for? A: A QSFP+ LR4 module is a 40GBASE-LR4 optical transceiver that uses four 10 Gbps lanes to provide 40 Gbps Ethernet over single-mode fiber for long-reach connections between data centers, campus networks, and backbone links.
• Q: What type of fiber is required? A: Single-mode fiber (SMF) is required for LR4 operation to achieve the advertised reach and performance.
• Q: How far can this module reach? A: Reach can vary with fiber quality and installation, but LR4 transceivers typically support distances up to about 10 kilometers on standard SMF; actual distance should be validated in your link budget calculation.
