Removing the CI
Follow these steps to remove the CI:
Step 1
Turn OFF the system power switch and disconnect the power cable from the power source.
Step 2
Attach an ESD-preventive strap (your own or the one supplied with the FRU) between you
and an unpainted chassis surface.
Step 3
Refer to Figure 12 and locate the CI board, which is mounted to the back of the backplane.
The CI is oriented vertically, attached to the backplane via the edge connector, and is
located to the right of the dual arbiter, as shown in Figure 12.
