Procedure
1.
Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.
2. Inspect the system processor socket area and remove any dust or debris (use a can of compressed air).
3. Lower the vacuum pen tool onto the system processor module to install. Fully press the top of the
pen (A) and hold the pen in the center of the system processor module as shown in Figure 69. Release
the top of the pen to fasten the pen onto the system processor module.
Note: To prevent the system processor module from falling, do not press the tip while holding the
pen and the system processor module. Minimize the time and distance that you have the pen holding
the system processor module in case the vacuum seal releases early.
4. Install the system processor module:
a. Lower the pen and system processor module onto the socket as shown in Figure 70 on page 60.
Align the beveled corner of the processor with the beveled corner on the socket. Use care to lower
the tool evenly without tilting the processor.
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.
