If you are replacing the fans, use needlenose pliers to pull each fan off the four grommets that mount it to the bracket, and remove the fans and cable from the bracket. Route the modem filter board cable out through the opening in the PCI divider. Disengage the cable from the cable guides on the PCI divider.
Power Mac G5 Take Apart 5. Slide the modem filter board back to disengage it from its mounting bracket, and remove the board and cable from the logic board. Replacement Note: When re-installing the modem filter board in its mounting bracket, be careful to engage the slots in the board with the edges of the bracket. Replacement Note: Be careful when rerouting the modem filter cable that it routes under the black connector for the front inlet fan and out through the correct opening in the PCI divider.
