Removing and Installing a Power Supply

Replacing a Power Supply

1

If you are adding a second power supply, remove the power supply blank. See "Removing a Power 
Supply" on page 54.

2

Holding the power-supply handle, slide the new power supply into the chassis until it is fully seated and 
contacts the system chassis. See Figure 3-7.

 

NOTICE: 

On a rack system, you may need to temporarily unlatch and lift the cable management arm. For 

information about the cable management arm, see the system’s Rack Installation Guide.

3

Insert the power cable through the cable retention bracket, connect the power cable to the power supply, 
and plug the cable into a power outlet.

 

NOTICE: 

For more information about the power cable retention bracket, see the Getting Started With Your 

System guide.

 

NOTE: 

After installing a new power supply in a system with two power supplies, allow several seconds for the 

system to recognize the power supply and determine its status. The power-supply status indicator turns green to 
signify that the power supply is functioning properly (see Figure 1-4).
