How to Install Black Box SFP 1250-Mbps Fiber with Extended Diagnostics

• Power down the host device or verify vendor guidance on hot-swapping before installation. If your equipment supports hot-swapping, you may insert the SFP module with the system powered on following the device’s established procedures; otherwise, power down to ensure a safe replacement.
• Identify an available SFP slot in the switch, router, or network appliance. Align the module with the slot and insert firmly until you feel or hear a click, indicating the module is seated and secured.
• Prepare the fiber connections. Use a clean, fiber-cleaning method to ensure LC connectors on both ends are free of dust and debris. Connect a 1310-nm multimode fiber cable with LC duplex connectors to the SFP’s LC ports, ensuring correct polarity and secure connections.
• Power on the device (or allow the port to reinitialize if hot-swapping was used). Observe the link status indicators on both ends; a solid link LED typically confirms a successful connection. If a link is not established, recheck fiber orientation, connector cleanliness, and slot compatibility.
• Access the device management interface to verify link status and begin monitoring Extended Diagnostics data. Use the network management system or CLI/GUI provided by your equipment to review transmitter and receiver health, optical power, and other available metrics to ensure the link operates at the expected rate and quality.
