computer and disconnect it from the mains power supply.
Setting the Jumpers
Your CD-ROM drive has a couple of jumper switches which must be correctly set before
the drive is installed.
The switches are towards the left as you look at the back of the drive. The settings of
these switches may need to be changed, depending on your needs. The two settings for
each switch are ON and OFF, sometimes referred to as 1 and 0. If the connector plug
connects the two pins, the switch is ON, if the connector plug touches only one pin, or
is not present, the switch is OFF.
The Setup Jumper
The Setup jumper switches look like this:
Interface connector
