Environmental Requirements And Specifications For Ex Series Switches - Juniper EX4500 Hardware Manual

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 22 on page 73 provides the required environmental conditions for normal switch operation.
