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.
