Network IDF racks play a critical role in distributing network connections within a building or campus. As the demand for network connectivity grows, so does the power consumption of network switches. Here are some key points to consider:

  1. Increased Power Usage:
    • Network switches now provide Power over Ethernet (PoE), which allows them to deliver power to connected devices (such as IP cameras, VoIP phones, and wireless access points) over the same Ethernet cable used for data transmission.
    • Over the past three years, the power requirements of network switches have increased due to the proliferation of PoE-enabled devices and the higher power draw of many of these devices such as WiFi 7 access points. All of this additional power creates even more heat.
  2. Battery Backup Demands:
    • As network switches draw more power, the need for properly sized, reliable battery backup systems (such as uninterruptible power supplies or UPS) becomes crucial.
    • Schools and businesses who want to ensure that their network infrastructure remains operational during power outages or disruptions must make sure the wiring closet UPS is sized to carry the load until power is restored. These larger UPS’s generate additional heat that must be removed from the wiring closet.
  3. Heat Generation:
    • High-power network switches generate significant heat, especially when operating at full capacity.
    • Overheating can lead to switch failures, reduced performance, and even safety hazards.
  4. Ventilation and Space Constraints:
    • Traditional broom closets or small spaces with poor ventilation are no longer suitable for housing network racks. Moving network closets is a major challenge, so schools and businesses may want to find alternate ways to cool these closets.
    • Schools and businesses must consider proper ventilation, space, and cooling solutions to prevent overheating.

Best Practices for Cooling IDF Closets

Here are some best practices to maintain optimal cooling in network closets and IDF racks:

  1. Choose the Right Location:
    • Place IDF racks in well-ventilated areas away from direct sunlight, heating vents, or other heat sources.
    • Avoid cramped spaces or closets with poor airflow.
  2. Active Cooling Solutions:
    • Install equipment racks with built-in cooling mechanisms, such as fans or air conditioning units.
    • Add cooling fans to your existing racks.
    • Add active heat exhaust fans to the room or the door to remove heat from the wiring closet.
    • Consider HVAC (ducted or ductless), heat exchangers, or oil immersion cooling systems. These may be ceiling mounted or wall mounted units.
  3. Monitor Temperature and Humidity:
    • Use environmental sensors to monitor temperature and humidity levels.
    • Set thresholds for alerts to prevent overheating or excessive humidity.
  4. Proper Cable Management:
    • Organize cables neatly to allow proper airflow.
    • Avoid cable congestion that obstructs ventilation.
  5. Regular Maintenance:
    • Clean dust and debris from equipment and vents.
    • Inspect fans and cooling systems periodically.
  6. Consider Redundancy:
    • Implement redundant cooling systems to ensure continuous operation.
    • Backup cooling solutions can kick in if the primary system fails.
  7. Plan for Growth:
    • Leave space in the rack design for additional equipment and cooling solutions.
    • Anticipate future power requirements and cooling needs.

Products from Eaton and Tripplite to help cool your network equipment rack


  • Eaton offers various cooling products suitable for network closets:
    • Rack-Mount Air Conditioners: These compact units can be mounted directly on the rack or cabinet. They provide localized cooling for specific equipment.
    • Cooling Fans: Eaton’s rack-mounted fans enhance airflow within the cabinet.

Tripplite – a division of Eaton

  • Tripplite also provides cooling solutions:
    • Wall-Mount Air Conditioners: These units are designed for small spaces like network closets. They can be wall-mounted to blow cool air directly into the closet.
    • In-Rack Cooling Units: Tripplite’s in-rack cooling solutions are ideal for individual racks or cabinets.
Tripplite in-rack cooling fan helps cool critical network equipment in your network closet.

Remember, cooling IDF racks is essential for network reliability, equipment longevity, and safety. Schools and businesses should invest in proper cooling infrastructure to avoid network disruptions and prevent costly failures.
