pin dual-row connector and supplies +5Vdc power in addition to data and
control signals; no separate cable is needed to power the drive.
A jumper (J7) is provided to configure the IDE channel for native (EIDE)
or legacy operation. Refer to J7 IDE Interface Configuration on page 6-9
for more information.
Polyswitches (Self-resetting Fuses)
The MBX series embedded controller draws +3.3Vdc, +5Vdc, and
+12Vdc power through power connector header J12. The +5Vdc power is
fused on board at its entry to the keyboard and mouse supply circuitry. The
+12Vdc power is fused on board at its entry to the LAN circuits on the
MBX. The following table lists the fuses with the voltages they protect.
The fuses are located on the secondary side of the board.
