Parallel Port, Floppy/Hard Disk Drive and SCSI
Connections
Note the following when connecting the floppy and hard disk drive cables:
•
The floppy disk drive cable has seven twisted wires.
•
A red mark on a wire typically designates the location of pin 1.
•
A single floppy disk drive ribbon cable has 34 wires and two connectors to
provide for two floppy disk drives. The connector with twisted wires always
connects to drive A, and the connector that does not have twisted wires
always connects to drive B.
Third Power Supply Failure

The system will notify you in the
event of a power supply failure.
This feature assumes that three
power supply units are installed in
the chassis, with one acting as a
backup. If you only have one or
two power supply units installed,
you should disable this with JP12
