HP uses three different power supply vendors. See the instructions below to disassemble and remove required power
supply components:
POWER SUPPLY 1:
a. Using dikes, cut the two plastic clamps that secure the wires to the power supply covers (see Figure 9).
b. Using a phillips screwdriver, remove the six screws that secure the cover to the power supply chassis - two screws
on back, two screws on the top, and two screws on the back (see Figures 8 & 9).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Lift the cover off the power supply. The cover you remove is in two pieces, and hinges connect the covers to the
power supply chassis.
d. Using dikes, cut all cables connected to the PCA in the power supply.
e. Remove the four screws that secure the power supply PCA to the chassis (see Figure 10).
f. Remove the power supply PCA from the power supply chassis.
g. Cut the small PCA from the large PCA (see Figure 10)
g. Cut eight capacitors from the PCA, as shown in Figure 10.
POWER SUPPLY 2:
a. Using dikes, cut the plastic clamp that secures the wires to the power supply cover (see Figure 12).
b. Using a phillips screwdriver, remove the six screws that secure the cover to the power supply chassis - two screws
on back, two screws on the top, and two screws on the back (see Figures 11 & 12).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Lift the cover off the power supply. The cover you remove is in two pieces, and hinges connect the covers to the
power supply chassis.
d. Using dikes, cut all cables connected to the PCA in the power supply.
e. Remove the four screws that secure the power supply PCA to the chassis (see Figure 13).
f. Remove the power supply PCA from the power supply chassis.
g. Cut 6 capacitors from the PCA, as shown in Figure 14.
POWER SUPPLY 3:
a. Using dikes, cut the plastic clamp that secures the wires to the power supply cover (see Figure 16).
b. Using a phillips screwdriver, remove the six screws that secure the cover to the power supply chassis - two screws
on back, four screws on the top, and two screws on the back (see Figure 15 & 16).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Lift the cover off the power supply. The cover you remove is in two pieces, and hinges connect the covers to the
power supply chassis.
d. Using dikes, cut all cables connected to the PCA in the power supply.
e. Remove the four screws that secure the power supply PCA to the chassis (see Figure 17).
f. Remove the power supply PCA from the power supply chassis.
g. Cut the small PCA from the large PCA (see Figure 18)
h. Cut 2 capacitors from the PCA, as shown in Figure 18.
