WARNING: Ensure that the cable does not drape where people could trip over it.
Connecting AC Power to a QFX5120 Switch
The QFX5120 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 191).
•
Ensure that you have connected the switch chassis to earth ground.
