Removing the Power Supply
CAUTION:
Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before performing any
procedure, see your Product Information Guide for complete information about
safety precautions, working inside the computer and protecting against
electrostatic discharge.
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 following power
cables:
• P1 and P2 to the system board
• P3 and P5 to the SATA or SAS drives
• P7 to the diskette drive
• P8, P9, and P10 to the optical and tape 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.
5 Tilt the heat sink and shroud assembly away from the fan housing and lift
it out.
6 Remove the I/O panel and SATA cables (if present) attached to the
routing clips on the side of the power supply.
