Removing the Power Supply
CAUTION: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
1
Turn off the system and attached peripherals, and disconnect the system
from the electrical outlet.
2
Open the system. See "Opening the System" on page 47.
3
Depending on your system configuration, disconnect the power cables
from the following components where applicable (see Figure 6-2 for
connector locations):
• PWR_CONN connector on the system board
• 12V connector on the system board
• Hard drives
• Diskette drive
• Tape backup unit
• Optical drives
NOTE: Note the routing of the DC power cables underneath the tabs in the
system frame as you release the tabs and remove the cables from the system
board and drives. You must route these cables properly when you replace
them to prevent their being pinched or crimped.
4
Remove the heat sink and shroud assembly. Loosen the two captive screws
holding the heat sink and shroud assembly in place.
These captive screws are adjacent to the processor cooling fan housing. See
Figure 3-21.
