ACX5000 Router Environmental Specifications

The router must be installed in a rack or cabinet. It must be housed in a dry, clean, well-ventilated, and
temperature-controlled environment.
Follow these environmental guidelines:
The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the
efficiency of the router cooling system.
Maintain ambient airflow for normal router operation. If the airflow is blocked or restricted, or if the
intake air is too warm, the router might overheat, leading to the router temperature monitor shutting
down the device to protect the hardware components.
Table 26 on page 83 provides the required environmental conditions for normal router operation.
