Environmental considerations

A

Environmental considerations

 lists the acceptable environmental ranges for both operating and nonoperating (such as 

during transportation or storage) conditions.

Cooling system and fans

Fans cool the CPU, main memory, and voltage regulators. For Brocade ICX 6650 switches, the fans 
use either:

•

An exhaust airflow which moves air from front to back. See 

. Devices with exhaust 

airflow are labeled with a green arrow with “E.” See 

.

•

An intake airflow which moves air from back to front. See 

. Devices with intake airflow 

are labeled with an orange arrow with “I.” See 

.

CAUTION

Be sure that the airflow direction of the power supply unit matches that of the installed fan tray. 
The power supplies and fan trays are clearly labeled with either a green arrow with an “E” for 
exhaust, or an orange arrow with an “I” for intake.
