6. Reinstall the heat sinks (see “Replacing a microprocessor and heat sink” on
page 274).
Note:
a. 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.
b. Use an alcohol wipe to remove any thermal grease from the tabs on the
microprocessor bracket frame on the old system board.
c. Use the microprocessor tool that comes in the system board FRU to
remove and replace microprocessors.
d. 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.
7. Reinstall the microprocessor air baffle (see “Replacing the microprocessor air
baffle” on page 210).
8. Reinstall the USB embedded hypervisor flash device, if you removed it earlier
(see “Replacing a USB embedded hypervisor flash device” on page 237).
9. Reinstall the PCI riser-card assembly, if any were installed (see “Replacing a
PCI riser-card assembly” on page 259).
10. Reinstall any adapters that were removed from the system board, if you
removed them earlier (see “Replacing an adapter” on page 213).
11. Reinstall the RAID cache cards, if you removed them earlier (see “Replacing a
RAID cache card” on page 252).
12. Reinstall the 10 Gb Ethernet adapter, if you removed it earlier (see “Replacing
the IBM Dual port 10Gb-T (copper) Ethernet Adapter or the IBM Dual port
10Gb SFP+ (fibre) Ethernet Adapter” on page 247).
13. Reinstall the power interposer card assembly, if you removed it earlier (see
“Replacing a power interposer redundant power supply card assembly” on
page 264).
14. Reconnect the cables that you disconnected earlier to the system board.
15. Reconnect the remote RAID battery cables and flash power module cables to
the adapters and install the RAID batteries in the trays located on the top of
the front USB/video assembly, if you removed them earlier.
16. Reinstall DIMM air baffle, if one was installed (see “Replacing the DIMM air
baffle” on page 211).
17. Reinstall the microprocessor and memory expansion tray, if one was installed
(see “Replacing the microprocessor and memory expansion tray assembly” on
page 279).
18. Slide the power supplies back into the bays until they click into place.
19. Reinstall the backplanes and cables, if you removed them.
20. Reinstall the fan cage assembly (see “Replacing the fan cage assembly” on
page 246).
21. Reinstall the cover (see “Replacing the server top cover” on page 207).
22. Slide the server into the rack.
23. Reconnect the power cords and any cables that you removed.
24. Turn on the peripheral devices and the server.
