Overview

The Expansion Modules attached to the Expansion Bus (not host bus)
Cables must be externally powered using a separate power supply. If
an EBC is installed, this optional power supply is purchased
separately and must be connected to the first (left most) module on the
Expansion Bus (see Figure 1-8).
By connecting the PS-4 Power Supply to the first Module, power is no
longer drawn from the host computer. All Expansion Modules
directly mated to one another from the first Module are supplied
power from the PS-4. The PS-4 can supply power for up to four
Expansion Modules.
