|
Thermal |
A minimum airflow of 79.8 cubic meters/hour (47 cubic ft/min.) available in
the immediate vicinity of the switch Note: Although this airflow may exceed the airflow maximum
listed in the device Technical Specifications, the additional airflow is recommended to pressurize
the inlet (cool isle) side of rack installations relative to the exhaust side to minimize
recirculation of hot air back to the inlet side.
Ambient air temperature not exceeding 40°C (104°F) while the switch is operating |
