Installing a Power Supply in a QFX5100 Device
The QFX5100 is shipped from the factory with two power supplies. Each power supply is a hot-removable
and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running.
You can install replacement power supplies in the two slots next to the fan modules without powering off
the switch or disrupting the switching function.
•
Before you install a power supply in a QFX5100 device, ensure that you have taken the necessary
precautions to prevent electrostatic discharge (ESD) damage (see “Prevention of Electrostatic Discharge
Damage” on page 242).
•
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 Device for
more information.
