17.4.2 Removing the CMU
This section describes the procedure for removing the CMU.
  1. Remove the PCIe cables from the cable guide.
    Remove the PCIe cables from the cable guide. When the CMUU is not mounted, this step is not necessary. Proceed to step 6.
Figure 17-8  Removing the PCIe Cables From the Cable Guide
Figure 17-8 Removing the PCIe Cables From the Cable Guide
Caution - Hold the PCIe cables with both hands to carefully remove the cables from the cable guide. If excessive force is used to pull out the PCIe cables, the cables may break or the connectors may be damaged.
  1. Remove the PCIe cables from the CMUL.
    The latch of the PCIe cable connector is located on the underside of the connector. Pull out the connector by pinching the connector hood while pushing the latch.
Caution - Remove the PCIe cable connectors carefully. If you roughly remove them, the PCIe cable may break or the connector may be damaged.
Figure 17-9  Removing the PCIe Cable Connectors
Figure 17-9 Removing the PCIe Cable Connectors
  1. Bundle the PCIe cables using the cable clamps of the CMUU.
    Bundle the PCI0 and PCI1 cables and the PCI2 and PCI3 cables into pairs respectively using the cable clamps (A in Figure 17-10) in such a way that they cross each other.
Figure 17-10  Securing the PCIe Cables With the Cable Clamp
Figure 17-10 Securing the PCIe Cables With the Cable Clamp
Caution - When removing either the CMUL or CMUU or both, be sure to bundle the PCIe cables using the cable clamps. Removing the CMU without bundling PCIe cables may damage the cables due to interference with the internal components.
  1. Loosen the fixing screws of the CMUU levers.
  1. Loosen the fixing screws (A in Figure 17-11) of the CMUU levers.
    Note that, if you do not remove the CMUU, this step is not necessary. Proceed to step 6.
Figure 17-11  Fixing Screws of the CMUU Levers
Figure 17-11 Fixing Screws of the CMUU Levers
Caution - Loosen the fixing screws carefully with the screwdriver so as not to damage the PCIe cables or the radiator located behind the PCIe cables.
  1. Remove the CMUU.
Note - To remove the CMU filler unit, proceed to step 6.
  1. a. Hold the CMUU levers (A in Figure 17-12), pull out the CMUU to the tip of "NEAR to END", and then hold it at "HANDLING POSITION" (B in Figure 17-12) on its side.
  1. b. Hold the CMUU at HANDLING POSITION, and remove it from the server.
Figure 17-12  Removing the CMUU
Figure 17-12 Removing the CMUU
Note - When removing the CMUU, be sure to bundle the PCIe cables using the cable clamps.
Note - If you do not remove the CMUL, the following steps are not necessary.
  1. Remove the filler unit.
    When the filler unit is not mounted, this step is not necessary. Proceed to step 7.
  1. a. Hook your fingers over the top part of the CMU filter unit (A in Figure 17-13) by inserting them into the gap there.

    b. Pull out the CMU filler unit by pulling it toward you.

Figure 17-13 Gap in the Top Part of the CMU Filler Unit
Figure 17-14  Removing the CMU Filler Unit
Figure 17-14 Removing the CMU Filler Unit
Note - When removing the CMU filler unit, hold it with both hands so that you do not drop it.
Note - If you do not remove the CMUL, the following steps are not necessary.
  1. Loosen the fixing screws of the CMUL levers.
    Loosen the fixing screws (A in Figure 17-15) of the CMUL levers.
Figure 17-15  Fixing Screws of the CMUL Levers
Figure 17-15 Fixing Screws of the CMUL Levers
  1. Remove the CMUL.
  1. a. Hold the CMUL levers (A in Figure 17-16), pull out the CMUL to the tip of "NEAR to END", and then hold it at "HANDLING POSITION" (B in Figure 17-16) on its side.
  1. b. Hold the CMUL at HANDLING POSITION, and remove it from the server.
Figure 17-16  Removing the CMUL
Figure 17-16 Removing the CMUL
Caution - You need to pull out the CMUL completely from the server before lifting it up. Lifting up the CMUL before pulling it out completely may damage the CMUL due to interference with the internal components.
Note - After removing the CMUL from the server, place it horizontally on the workbench gently to avoid mechanical shock.
