QFX5240 Environmental Requirements and Specicaons
You must install the switch in a rack and house it in a dry, clean, well-venlated, and temperature-
controlled environment.
Follow these environmental guidelines:
• The site must be as dust-free as possible, because dust can clog air intake vents and lters, reducing
the eciency of the switch cooling system.
• Maintain ambient airow for normal switch operaon. If the airow is blocked or restricted, or if the
intake air is too warm, the switch might overheat. As a result, the switch temperature monitor might
shut down the device to protect the hardware components.
