Environmental Requirements and Specifications for an NFX250 Device


The device 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 device cooling system.

  • Maintain ambient airflow for normal operation of the device. 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 1 provides the required environmental conditions for normal operation of the device.

Table 1: NFX250 Device Environmental Tolerances




No performance degradation up to 6000 feet (1828 meters) at 86° F (30° C)

Relative humidity

Normal operation ensured in relative humidity range of 5% through 90%, noncondensing


Normal operation ensured in temperature range of 32° F through 122° F (0° C through 50° C)


Complies with Zone 4 earthquake requirements as per GR-63, Issue 4
