Environmental Requirements and Specifications for VXA1000 Series Media Flow Engines

The appliance must be installed in a rack housed in a dry, clean, well-ventilated, and temperature-controlled environment.

Ensure that these environmental guidelines are followed:

  • The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the efficiency of the appliance cooling system.
  • Maintain ambient airflow for normal appliance operation. If the airflow is blocked or restricted, or if the intake air is too warm, the appliance might overheat, causing the appliance temperature monitor to power off the appliance to protect the hardware components.

Note: Install VXA1000 Series Media Flow Engines only in restricted areas, such as dedicated equipment rooms and equipment closets, in accordance with Articles 110–16, 110–17, and 110–18 of the National Electrical Code, ANSI/NFPA 70.

Table 1 lists the required environmental conditions for normal appliance operation.
