The power supplies in a QFX5100 switch are hot-removable and hot-insertable
field-replaceable units (FRUs): you can remove and replace them without powering off
the switch or disrupting switch functions.
•
Before you install a power supply in a QFX5100 switch, ensure that you have taken the

“Prevention of Electrostatic Discharge Damage” on page 142 ).
• Ensure that the airflow direction of the power supply is the same as the chassis. Labels
on the power supply handle indicate the direction of airflow. See
“Cooling System and
Airflow in a QFX5100 Switch” on page 25 for more information.
