Note 6: DC Power Details for J7
Warning: Never remove or install any hardware component with the computer
power on. Never connect a floppy drive power cable to J7 when the computer is
powered on.
•
Connect the PC floppy drive power connector to J7 so as to supply DC power to the External
Signal connectors. Both 5Vdc and 12Vdc are available on J1 or on the DB37 External Signals
Bracket Assembly.
•
Both the 5Volt and 12Volt power pins have a 1.5 amp re-settable fuse on the board. If the fuse
is tripped, turn off the host computer power. When the computer is turned on again, the fuse is
automatically reset.
