Color Indicator Airflow Direction Product Number Model
Juniper gold handle Airflow Out (port-to-FRU) JPSU-1600W-AC-AFO QFX5220-128C
CAUTION: Verify that the airflow direction on the power supply handle matches the
direction of airflow in the chassis. Ensure that each power supply you install in the chassis
has the same airflow direction. If you install power supplies with two different airflow
directions, Junos OS raises an alarm. If you need to convert the airflow pattern on a
chassis, you must change out all the fans and power supplies at one time to use the new
direction.
To avoid electrical injury, carefully follow instructions in “Connecting the QFX5220 to Power” on page 136 .
