Removing An Ac Power Supply; Removing An Hvac/Hvdc Power Supply - Cisco Nexus 9396PX Hardware Installation Manual

Replacing Modules
You can replace a power supply with any other power supply that is supported by the same switch so long as
it provides the same direction of airflow as the fan modules installed in the switch and uses the same type of
power source as the other power supply installed in the switch (do not mix AC, DC, and HVAC/HVDC power
supplies in the same switch). The coloring of the latch handle on the power supply indicates the airflow
direction as explained in the following table that lists the supported power supplies for this switch.
