Overview of Racks

You can install the switch in the following types of cabinets and racks, assuming an external ambient air
temperature range of 0 to 104°F (0 to 40°C):
• Standard perforated cabinets
• Solid-walled cabinets with a roof fan tray (bottom to top cooling)
• Standard open racks

If you are selecting an enclosed cabinet, we recommend one of the thermally validated types, either standard
perforated or solid-walled with a fan tray.
