NOTE: In EU countries, Egypt, Nigeria, Saudi Arabia, Serbia, South Korea, and South Africa, you
must ensure that the redundant power supply is installed in the switch chassis.
To prevent electrical injury while installing or removing AC power supplies, carefully follow instructions
in “Installing an AC Power Supply in an EX4300 Switch” on page 465 and Removing an AC Power Supply from
an EX4300 Switch.
AC Power Supply Airflow
Each power supply has its own fan and is cooled by its own internal cooling system.
Each power supply has a label AIR OUT (AFO) or AIR IN (AFI) on the faceplate of the power supply that
indicates the direction of airflow in the power supply.
Table 53 on page 174 lists the AC power supply models and the direction of airflow in them.
