Environmental Requirements and Specifications for Junos Space Appliances

 

This topic applies to the following Junos Space Appliances: JA1500 and JA2500.

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

Ensure that the following environmental guidelines are followed:

  • Keep the site 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.

Table 14 provides the required environmental conditions for normal appliance operation and Table 15 the environmental specifications for storing the appliance (nonoperational).
