Environmental Requirements and Specifications for a QFX5100 Switch
The switch must be installed in a rack or cabinet. 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 14 on page 47 provides the required environmental conditions for normal switch
operation.
