Each expansion carrier requires a power supply.
The added power supply can cause excessive noise in the module occupying
the next slot. To eliminate this noise, install a copper foil shield to the power
supply as indicated in this procedure. These shields and their labels are
packaged in the power unit shielding kit included with the expansion carrier.
See Figure 2-11.
