Installing optical modules on the server

To add an optical module to a server, you must ensure compatibility with the server's network adapter, follow ESD safety precautions, and properly insert the module and optical cable into the designated port.

Compatibility and Preparation

Before installation, confirm the type of optical module compatible with your server's network adapter (NIC). Servers typically do not have direct optical ports; instead, optical modules are inserted into NICs, which are then installed in PCIe slots of the server.

Popular NI

C manufacturers include Intel, Broadcom, Mellanox, and QLogic, each with specific module compatibility requirements. Select the correct module type (SFP, SFP+, QSFP28, etc.) based on your network speed and distance requirements. Wear an ESD wrist strap and work on an ESD-safe mat to prevent electrostatic discharge, which can damage sensitive optical components.

Keep dust caps on the module and cable connectors until ready to connect.

Installation Steps

Remove Existing Components: If replacing an old module or cable, carefully remove it by pressing the latch or release mechanism without forcing the component. Insert the Optical Module: Remove the dustproof plug from the NIC port and gently insert the optical module until it clicks securely into place. Connect the Optical Cable: Remove the dust cap from the optical cable and insert it into the module port.

Ensure the connector clicks and cannot be pulled out easily. Label and Route Cables: Number and label the cable ends to match the connected devices. Route cables neatly, maintaining a minimum bend radius (typically 4 cm) and separating them from power or signal cables to prevent damage.

Verify Connection: Check that the server recognizes the module and that the link is active.

Some NI

Cs may require driver or firmware updates to support new modules.

Safety and Maintenance

Handle modules by the sides or metal cage; avoid touching gold contacts or optical bores. Keep dust caps on unused ports to prevent contamination. Avoid excessive force when inserting or removing modules to maintain port integrity.

Ensure proper labeling and cable management for future maintenance and expansion. By following these steps, you can safely add an optical module to your server, enabling high-speed fiber connectivity while minimizing the risk of hardware damage or link failure.
