DC Power Supply in a QFX5100 Device

Copyright © 2017, Juniper Networks, Inc.
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.
Table 18 on page 55 shows the different power supplies and their direction of airflow.
