− 

The blower begins operating immediately. 

− 

The power supply/blower assembly LED is green. 

 

Hot-Plug Power Supply 

Observe the following conditions for AC power supplies: 

  CAUTION:  Removing a power supply significantly changes 

the airflow within the chassis. The storage system will shut down to 
prevent overheating unless the power supply is replaced within 
5 minutes. 

  CAUTION:  Handle the blower carefully to avoid damaging the 

housing: 

• 

Do not press on the center section of the blower because this action 
can damage the blades. Press only on the outer edge of the blower. 

• 

Do not rest the power supply on the blower because the weight of 
the power supply can damage the blower housing. 

To remove the component: 

1.  Disconnect the power cord from the power supply. 

2.  Remove the blower ("Blower" on page 

16

).
