Installation & Usage Tips
- Hot-swappable Design: The SFP-H25G-CU5M is fully hot-swappable—insert or remove the cable without powering down your equipment.
- Plug and Play: No additional configuration or software required. Simply insert into compatible SFP28 ports.
- Proper Handling: Always hold the cable by the connectors and avoid excessive bending. Maintain a minimum bend radius of 30mm to ensure signal integrity.
- Port Cleaning: Ensure the SFP28 cages are free of dust and debris before installation.
- Lock Mechanism: Use the integrated pull-tab for secure installation and easy removal; do not force or twist the cable.
- Stacking Cables: Avoid tightly bundling or sharply bending cables to prevent signal loss or physical damage.
- Operating Conditions: Confirm that the cable is used within specified operating temperature (0 to 70°C) and humidity levels.
- Compatibility: For optimal performance, use Cisco certified cables with Cisco switches and servers, and refer to the latest compatibility matrix for your platform.
