5. Setup and Installation

5.1 Mounting the Fan Unit

The Tecmojo 1U 2-Fan unit is designed for standard 19-inch rack mounting. It occupies 1U of rack space. The unit comes with removable mounting brackets, offering flexibility for installation.

1. Identify Rack Location: Choose an appropriate 1U space within your 19-inch rack or cabinet. For optimal cooling, consider placing the unit where it can effectively exhaust hot air or draw in cool air, depending on your cabinet's airflow design.
2. Prepare Rack Rails: If your rack rails require cage nuts, install four M6 cage nuts into the square holes on the front and rear rack rails where the fan unit will be mounted.
3. Position the Unit: Align the mounting holes on the fan unit's brackets with the holes on your rack rails.
4. Secure the Unit: Use the provided M6*12 screws and M6 plastic gaskets to secure the fan unit to the rack rails. Ensure the screws are tightened firmly to prevent movement, but do not overtighten.

7. Maintenance

Regular maintenance ensures the longevity and efficient operation of your cooling system.

• Cleaning: Periodically inspect the fan grilles for dust accumulation. Use a soft brush or compressed air to gently clean the fan blades and grilles. Ensure the unit is powered off and unplugged before cleaning.
• Inspection: Check the power cord for any signs of damage or fraying. Ensure all mounting screws remain tight.
• Airflow: Ensure that the air intake and exhaust paths within your cabinet are not obstructed by cables or other equipment.

8. Troubleshooting

If you encounter issues with your Tecmojo 1U 2-Fan Rack Cabinet Cooling System, refer to the following common problems and solutions:

• Fan Not Turning On:
  • Ensure the power cord is securely plugged into a live outlet.
  • Verify the ON/OFF switch is in the 'ON' position and illuminated.
  • Check the power source (outlet or PDU) for functionality.
• Insufficient Cooling:
  • Ensure fan grilles are free from dust and obstructions.
  • Verify proper airflow direction within your cabinet. Consider if the fan is positioned to exhaust hot air effectively.
  • Check if the cabinet is adequately sealed to prevent hot air recirculation.
• Unit Feels Loose in Rack:
  • Re-tighten the M6 mounting screws.
  • Ensure the mounting brackets are correctly aligned with the rack rails.
  • If using only one mounting hole per side, consider adding additional support or ensuring the screws are robust enough for the weight and leverage.
