PREPARING THE SMARTDRIVE
Before you install a SmartDrive, you must configure it for use in the
computer.
NOTE: The drive type number and non-standard drive configuration data are
printed on a label on the drive. Record this information before beginning
installation. You will need this information when you configure your system
using the setup utility.
The SmartDrive has three pairs of jumper pins (Jumper Block J8) near the
connectors at the rear of the drive.
A jumper is a clip that contains metal contacts. To install a jumper, place it
over two adjacent pins. This installation connects or bypasses a circuit,
enabling or disabling a function.
Decide which drive configuration is best for your system. Refer to the
following diagram and table to install the appropriate jumper.
The following table summarizes the jumper settings:
