CAUTION: Verify that the airflow direction of 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, and
the status (
OK/!
Table 21 on page 114 shows the different power supplies and their direction of airflow.
To avoid electrical injury, carefully follow instructions in
QFX3500, QFX3600, or QFX3600-I Device" on page
DC Power Supply LEDs on a QFX3500, QFX3600, or QFX3600-I Device on page 754

For installations that require a separate grounding conductor to the chassis, the device
must be adequately grounded before power is connected to ensure proper operation
and to meet safety and electromagnetic interference (EMI) requirements. To ground a
QFX3500 device, connect a grounding cable to earth ground and then attach it to the
chassis grounding points.
