19. Repeat from step "5" on page 86 with the other system processor module.
20. Place the dust covers on the system processor module sockets on the old system backplane.
The following steps continue installing components into the new system backplane:
21. Using your labels, replace the power switch cable and the front USB cable into their connectors on
the system backplane.
For instructions, see "Replacing the power switch and cables in the 9183-22X system" on page 74.
22. Transfer the trusted platform module from the old system backplane to the new system backplane.
For instructions, see "Removing the trusted platform module card from the 9183-22X system" on
page 132.
23. Transfer the time-of-day battery from the old system backplane to the new system backplane.
For instructions, see "Removing and replacing the time-of-day battery in the 9183-22X system" on
page 128.
24. Transfer the memory modules from the old system backplane to the new system backplane.
For instructions, see "Removing and replacing memory modules from the 9183-22X system" on page
23.
25. Replace the power distribution board.
For instructions, see "Replacing the power distribution board in the 9183-22X system" on page 63.
26. Using your labels, replace the PCIe adapters and PCIe risers.
For instructions, see "Replacing a PCIe adapter in the 9183-22X system" on page 44.
27. Replace the drive cable holder on the left side of the system by using the following procedure.
