2.3 Installation Considerations
• Do not install rack slides on the sides of the chassis. Rack slides block airflow
to the cooling fans inside the unit.
• Make sure that there is sufficient space for airflow at the sides of the unit.
• In racks where heat is high, make sure to install forced air cooling at the top or
bottom of the rack.
• Do not let the temperature inside the rack exceed 50°C (122°F).
