Without the disk drive power connector installed, the +5 V supply and the
DIO lines share the same power source. In this case, use the following
equation to determine the current available at the +5 V terminal. In the
equation, I
DIO
is the total current sourced on all DIO lines.
I
+5V
= 1.2 A

With the disk drive power connector installed, the current at the +5 V
terminal is supplied by an external power source. In this case, the current at
the +5 V terminal can be up to 1 A.
