• Make sure that the socket covers from the microprocessor frame brackets on the new system
board were placed on the microprocessor sockets on the old system board that you removed.
• Use an alcohol wipe to remove any thermal grease from the tabs on the microprocessor bracket
frame on the old system board.
• Use the microprocessor tool that comes in the system board FRU to remove and replace
microprocessors.
• Remove and keep the heat sink and microprocessor from each microprocessor socket of the old
system board together and install them on the new system board on the same socket together.
For example, when you removed the heat sink and microprocessor from microprocessor socket
1 of the old system board , you installed them both on the same socket (socket 1) on the new
system board.
Step 7.
Reinstall the microprocessor air baffle (see “Replacing the microprocessor air baffle” on page 219).
Step 8.
Reinstall the USB embedded hypervisor flash device, if you removed it earlier (see “Replacing a
USB embedded hypervisor flash device” on page 245).
Step 9.
Reinstall the PCI riser-card assembly, if any were installed (see “Replacing a PCI riser-card
assembly” on page 271).
Step 10. Reinstall any adapters that were removed from the system board, if you removed them earlier (see
“Replacing an adapter” on page 223).
Step 11. Reinstall the RAID cache cards, if you removed them earlier (see “Replacing a RAID cache card” on
Step 12. Reinstall the Ethernet adapter, if you removed it earlier (see “Replacing the Intel I350-T4 ML2 Quad
Port GbE Adapter for IBM System x” on page 255 or “Replacing the ML2 Dual-port 10Gbase-T
Adapter for IBM System x or ML2 Dual-port 10 GbE SFP+ Adapter for IBM System x” on page 257).
Step 13. Reinstall the power interposer card assembly, if you removed it earlier (see “Replacing a power
interposer redundant power supply card assembly” on page 276).
Step 14. Reconnect the cables that you disconnected earlier to the system board.
Step 15. Reconnect the remote RAID flash power module cable to the adapter and install the RAID flash
power module in the trays located on the top of the front USB/video assembly, if you removed it
earlier.
Step 16. Reinstall the DIMM air baffle, if one was installed (see “Replacing the DIMM air baffle” on page 221).
Step 17. Reinstall the microprocessor and memory expansion tray, if one was installed (see “Replacing the
microprocessor and memory expansion tray assembly” on page 293).
Step 18. Slide the power supplies back into the bays until they click into place.
Step 19. Reinstall the backplanes and cables, if you removed them.
Step 20. Reinstall the fan cage assembly (see “Replacing the fan cage assembly” on page 253).
Step 21. Reinstall the cover (see “Replacing the server top cover” on page 216).
Step 22. Slide the server into the rack.
Step 23. Reconnect the power cords and any cables that you removed.
Step 24. Turn on the peripheral devices and the server.
Important:
Perform the following updates:
• Update the server with the latest RAID firmware or restore the pre-existing firmware from a CD or DVD
image.
• Update the UUID and the DMI/SMBIOS (see “Updating the Universal Unique Identifier and DMI/SMBIOS
