Floppy Connector - Supermicro X7SLM+ User Manual

Floppy Connector

The floppy connector is located next
to COM2 Connector on the mother-
board. See the table on the right for
pin definitions.
Note the following when con-
necting the floppy cable:
• 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 con-
nectors 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.
