Cooling system and fans

The 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. Refer to the first figure below. Devices with
exhaust airflow are labeled with a green arrow with an “E.”

An intake airflow which moves air from back to front. Refer to the third figure below. Devices with
intake airflow are labeled with an orange arrow with an “I.”
