Before You Begin
A front fan tray is located inside each of the power supplies. You must remove the power supply to replace the fan tray.
Caution - Do not leave a power supply slot empty. Power supplies have integrated fans that continue to supply cooling air even when the power supply is off.
Follow the instructions in Remove a Power Supply.
Pull the power supply out of the system just far enough to access the fan. You do not need to remove the power supply completely from the system.
Caution - The fan continues spinning for a moment after the power supply is disconnected. Be careful not to insert a finger or other object into the fan while the fan is still spinning.
Caution - You must power off the chassis or replace the power supply within one minute in order to ensure proper system cooling and operation.
