The airflow direction of the power supply must match that of the installed fan assemblies. All must be either exhaust or intake.
NOTE
Power supplies are hot-swappable. However, they should be inserted or removed without a power cord being connected to a
power source to avoid damage.
CAUTION
Ensure that the airflow direction of the power supply unit matches that of the installed fan tray. The power supplies and fan
trays are clearly labeled with either a green arrow with an "E", or an orange arrow with an "I."
