The QFX5200 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.
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
Ensure that you have connected the switch chassis to earth ground.
