Disconnect the 4-pin cable from the header labeled P202 on the left
side of the power supply circuit board.
As shown in Figure 2-10, you may need to pry back the clip to free the
cable.
Disconnect the other cable from the header labeled P101 on the right
side of the power supply circuit board.
As shown in Figure 2-10, you need to grip this cable firmly and pull
forcefully.
Remove the four screws from the ring generator as shown in
Figure 2-10.
Remove the ring generator.
Position the replacement ring generator as shown in Figure 2-10 and
align the screw holes.
Make sure the
P1
header on the ring generator is on the same side of
the power supply housing as the
P101
header on the circuit board.
Replace the four screws and fasten them to secure the ring generator.
Connect one end of the new ring generator’s cable with the 3-pin
connectors to the header labeled P101 on the power supply circuit
board.
This cable connector, as with all four of the cable connectors, is
“keyed” so that you cannot attach it to the header if it is turned the
wrong way.
