QFX5110 Cooling System and Airflow Description
The cooling system in an QFX5110 device consists of five fan modules and a single fan
in each power supply. The switch can be set up to work in one of two airflow directions:
•
Airflow In–Air comes into the switch through the vents in the field-replaceable units
(FRUs)
•
Airflow Out–Air comes into the switch through the vents in the port panel.
All QFX5110 switches, except the QFX5110-32Q-CHAS, are shipped with five fan modules
and two power supplies. Order fans for the QFX5110-32Q-CHAS separately.
CAUTION: Airflow In and Airflow Out fans and power supplies cannot be
mixed in the same chassis.
