Figure 91. Preparing for system processor module installation
12. Install the system processor module in the replacement system backplane:
a. Lower the tool and system processor module onto the socket. Align the beveled corner (A) of the
tool with the beveled corner on the socket. Ensure that the two guide pins (C) are inserted into
the alignment holes (B) on each side of the tool. Use care to lower the tool evenly without tilting
the tool. See Figure 92 on page 91.
Note: Do not attempt to slide the tool and the system processor module in any direction while
the system processor module is touching the socket. If the tool and the system processor module
are not aligned with the guide pins, lift the tool and the system processor module and reposition
them.
