Environmental Requirements and Specifications for the QFX3100 Director 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.
Table 20 on page 89 provides the required environmental conditions for normal device
operation.
