Switch Cooling Requirements

◆
Make sure that the unit is connected to a separate grounded power outlet and
is powered from an independent circuit breaker. As with any equipment, using
a filter or surge suppressor is recommended. Verify that the external AC power
requirements for the switch can be met as listed under
Specifications" on page
Wherever the switch is located, be sure to pay close attention to switch cooling
requirements. The location should be well ventilated and provide unrestricted
airflow at the front, back, and sides of the switch. If the airflow is insufficient, it may
cause the switch to overheat and possibly fail.
The switches support the following fans:
◆
ECS4620-28F/52T: two fans
◆
ECS4620-28P: three fans
◆
ECS4620-52P: four fans
The following figure shows the cool air intake and the hot air exhaust airflow into
and from the switch.
