c. With the removal tool (A) sitting on top of the system processor module, push down on the tool to
lock the system processor module into the tool as shown in Figure 184 on page 161. Make sure
that both of the tool jaws are locked on the system processor module. Do not press the blue
release tabs until directed to do so later.
Note: The tool drops slightly when you push down on the processor module so that the jaws can
grab the bottom of the module.
