16.5.3 Removing the motherboard unit
Caution - Remove all the memory before removing the motherboard unit. Otherwise, the memory may be damaged.
  1. Remove all the fan units.
    For details, see "15.3.2 Removing a fan unit."
Note - Make a note of the positions of the fan units before removing them to ensure that they are reinstalled correctly.
  1. Remove all the PCI Express (PCIe) risers.
    For details, see "8.3.2 Removing a PCI Express riser."
    Removing the PCIe risers enables you to easily remove the cables from the PSU backplane.
Note - Make a note of the mounting locations of the PCIe risers before removing them to ensure that they are reinstalled correctly.
  1. Remove all the memory.
    For details, see "16.5.2 Removing memory."
Note - Make a note of the mounting locations of memory before removing them to ensure that they are reinstalled correctly.
  1. Release the cable lock guide.
    For details, see "5.8.7 Releasing the cable guide lock."
    If the cable guide does not have a lock, proceed to step 3.
  1. Remove the cables connected to the motherboard unit.
    The following cables should be removed:
    a. Three (3) cables on the motherboard unit that connect the PSU backplane to the motherboard unit

    b. One (1) cable that connects the PSU backplane to the HDD backplane
    The cable does not have to be removed from the HDD backplane.

    c. Two (2) cables that connect the HDD backplane to the motherboard unit

    d. Two (2) cables that connect the operation panel to the motherboard unit
Note - Record the positions of the cables before removing them to ensure that they are reinstalled correctly.
