1. Read the safety information that begins on page “Safety” on page vii and
“Installation guidelines” on page 33.
2. Turn off the server (see “Turning off the server” on page 21) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables as necessary to replace the device.
3. If the server is in a rack, slide the server out of the rack.
4. Remove the server cover (see “Removing the server top cover” on page 206).
5. Remove the fan cage assembly (see “Removing the fan cage assembly” on
page 245
6. Remove the DIMM air baffle, if one is installed (see “Removing the DIMM air
baffle” on page 210).
7. Slide the power supplies out of the bays slightly to disengage them from the
connectors.
8. Remove the microprocessor and memory expansion tray, if one is installed
(see “Removing the microprocessor and memory expansion tray assembly” on
page 278).
9. Remove the microprocessor air baffle (see “Removing the microprocessor air
baffle” on page 209).
10. Disconnect all cables from the system board. Make a list of each cable as you
disconnect it; you can then use this as a checklist when you install the new
system board.
11. Disconnect all remote RAID battery cables or flash power module cables from
the adapters and remove the batteries or flash power module from the trays
located on top of the USB/video assembly, if any are installed (see “Removing
a RAID battery or flash power module” on page 249).
12. Remove the DIMMs from the system board and set them aside on a
static-protective surface for reinstallation (see “Removing a memory module”
on page 223).
Note: Make a note of the location of each DIMM as you remove it, so that
you can later reinstall it in the same connector.
13. Remove the RAID cache cards from the system board, if any are installed (see
“Removing a RAID cache card” on page 250).
14. Remove the power interposer card assembly, if one is installed (see
“Removing the power interposer for redundant power supply card assembly”
on page 264).
15. Remove the PCIe riser-card assembly, if it is installed (see “Removing a PCI
riser-card assembly” on page 258).
16. Remove any adapters that are installed on the system board (see “Removing
an adapter” on page 212).
17. Remove the 10 Gb Ethernet adapter, if one is installed (see “Removing the
IBM Dual-port 10Gb-T (copper) Ethernet Adapter or the IBM Dual-port 10Gb
SFP+ (fibre) Ethernet Adapter” on page 247).
18.
Remove the USB embedded hypervisor flash device (see “Removing a USB
embedded hypervisor flash device” on page 236).
19. Remove all heat sinks and microprocessors, and set them aside on a
static-protective surface for reinstallation (see “Removing a microprocessor
and heat sink” on page 272).
