QFX10000 Environmental Requirements and Specifications
The QFX10008 and QFX10016 modular switches must be installed in a four-post rack. It must be
housed in a dry, clean, well-ventilated, 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 filters, reducing
the efficiency of the switch cooling system.
• Maintain ambient airflow for normal switch operation. If the airflow is blocked or restricted, or if the
intake air is too warm, the switch might overheat, leading to the switch temperature monitor shutting
down the device to protect the hardware components.
Table 60 on page 158 provides the required environmental conditions for normal switch operation.
