Environmental Requirements and Specifications for EX Series Switches
The switch must be installed in a rack or cabinet 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 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 54 on page 125 provides the required environmental conditions for normal switch operation.
