Juniper Networks EX2200 manual EX Series Switch Environmental Tolerances, Description Tolerance

Chapter 4: Site Preparation

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 switch cooling system.

• Maintain ambient airflow for normal switch operation. If the airflow is blocked or restricted, or if the intake air is too warm, the switch might overheat, leading to the switch temperature monitor shutting down the switch to protect the hardware components.

Table 17 on page 37 provides the required environmental conditions for normal switch operation.

Table 17: EX Series Switch Environmental Tolerances
