Caution
Power supplies can become very hot during operation. Wear thermal protective gloves
when you remove a power supply from an operating switch.
Note
If you are not installing a replacement power supply, install a cover over the unoccupied
power supply bay. Unoccupied bays must always be covered to maintain proper system
ventilation and EMI levels.

the same airflow direction.
