How to Install StarTech.com Cisco GLC-LH-SMD Compatible SFP Module 10 Pack

• Power down the network device: Before installation, shut down the switch or router and disconnect powered cables to minimize the risk of ESD and hardware damage.
• Insert the SFP: Remove the SFP slot cover if present, align the module with the slot, and insert it firmly until it seats with a gentle click. Ensure the module is oriented correctly for the port and that there are no obstructions.
• Connect the fiber cable: Attach a compatible SMF fiber optic cable with LC connectors to the SFP module. Handle the fiber carefully, maintain clean connector ends, and verify the fiber path aligns with the link direction to avoid insertion loss.
• Reconnect power and test: Reconnect power to the device and reinsert cables. Check the link status on the device’s management interface or through LED indicators to confirm a healthy connection. If available, run a quick throughput test to validate performance.
• Monitor and verify: Use the device’s diagnostics (DDM/DOM) to verify optical power, temperature, and other critical metrics. If needed, update firmware on the host device or module to ensure optimal compatibility and stability.
