Table A–2 lists information for the board reference whose components on the
engineering silicon board differ from the production silicon board. Board reference F4
has been replaced with F84 while J8 has been combined with J7 in the production
silicon board.
Table 2–1 on page 2–2 shows the production silicon board components.
Table A–3 lists the power rail measurements whose values on the engineering silicon
board differ from the production silicon board. Table 2–22 on page 2–22 shows the
production silicon power rail measurements.
Banana Jacks and Fuses
In addition to the power supplied by the regulators, several power rails can be
directly supplied by an external bench-top power supply through the on-board
banana jacks (J2–J4, J7–J10).
Figure 2–11 on page 2–27 illustrates how external power
is allowed in through the banana jacks by first removing the fuses (F1–F7) associated
with the power rail to be externally supplied.
c
Failure to remove the associated fuses (F1–F7) or improperly setting the external
supply voltages too high can result in damage to the board.
