how to install StarTech.com Juniper RX-10KM-SFP Compatible SFP Module

• Power down the affected network device or follow your equipment’s hot-swapping procedures if supported, ensuring a safe environment for installation.
• Locate the SFP slot on your switch, router, or other compatible networking hardware. Remove any existing SFP module if you are replacing a failed unit.
• Align the SFP module with the slot and gently insert it until it clicks into place, making sure the HDMI-like latch mechanism engages securely.
• Connect the appropriate fiber patch cable to the LC duplex connector on the SFP module, selecting the correct fiber type (SMF or MMF) and ensuring the link ends match the corresponding port requirements (TX/RX fiber orientation).
• Power on the device (if not already on) and verify link activity via the device management interface or the status LEDs. Use the DDM data (if supported) to confirm optical power levels and module health.
• Perform a link test to confirm full-duplex 1 Gbps operation and verify performance metrics such as throughput, latency, and error rates. If issues arise, re-check fiber type, length, connectors, and polarity, and consult the device logs for any diagnostics.
