Connecting AC Power to a QFX5110

The QFX5110 is shipped with two 650 W power supplies pre-installed. 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 switch functions.
Ensure that you have a power cord appropriate for your geographical location available to connect AC
power to the switch.
Before you begin connecting AC power to the switch:
Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage
(see "Prevention of Electrostatic Discharge Damage" on page
