ACX2000 and ACX2100 Router Environmental Specifications

The router 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 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 router to protect the hardware components.
NOTE: Depending on the ambient temperature, it may take up to 5 minutes for the router to
heat up to the operating temperature.
Table 25 on page 73 provides the required environmental conditions for normal router operation.
