Environmental Requirements and Specifications for a QFX3500 Device
The device must be installed in a rack or cabinet 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 device cooling system.
•
Maintain ambient airflow for normal device operation. If the airflow is blocked or restricted, or if the
intake air is too warm, the device might overheat, leading to the device temperature monitor shutting
down the device to protect the hardware components.
provides the required environmental conditions for normal device operation.
