ACX2200 Router Environmental Specifications on page 41
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 19 on page 41
provides the required environmental conditions for normal router
operation.
