About this task
Procedure
1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged
into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Install the replacement system backplane.
a) Grasp the replacement system backplane by positions (A) and (B) on the front and middle metal
bulkheads and begin lowering the backplane into the chassis. As you lower the backplane, be
careful not to hit the pins (C) on the power supply cage. See the following image.

b) Tilt the backplane so that the front end is high and the back end is low as you continue to lower
the backplane into the chassis. When the system backplane catches on the pins (A) on the power
supply cage, lower the front end enough so that it clears the pins. See the following image.

b) If necessary, take the cover off of the system processor module tray.
c) Hold the sides of the tool with system processor module and carefully lift the tool out of the
system processor module tray.
d) Lower the tool and system processor module onto the socket. Align the beveled corner of the tool
with the beveled corner on the socket. Align the guide pins (A) with the alignment holes (B) on
each side of the tool. Use care to lower the tool evenly without tilting the tool.
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.
