 Spare jumper stored on pins 1-3


 Master/Slave jumper block
 --------------------------
 The jumper block accepts 2-mm (0.079-inch) jumpers. A spare jumper is
 attached to the jumper block. If you need additional jumpers, use
 Seagate part number 10562-001 or an equivalent.

 CAUTION
 If you use a jumper that is not the correct size, you may damage the
 jumper block and the jumper. Use the jumpers supplied with the drive.

 Single-Drive configuration
 --------------------------
 Use the factory-default jumpersetting when the Medalist drive is
 installed as the single drive in the computer.


 Two-Drive configuration
 -----------------------
 When two drives are installed in the computer, you must configure one
 drive as the master and the other as the slave.


 Cable-select configuration
 --------------------------
 If your computer and both of your drives support cable select (CSEL),
 you can use the cable select option to determine the master and
 slave. To configure your drives to use cable select, you need to
 install jumpers and to use a special cable-select cable as follows:

 - Install a jumper on pins 3 and 4 of the master/slave jumper block.
   When a jumper is installed in this position, the drive ignores the
   jumper installed on pins 7 and 8.

 - You must use an interface cable built for cable-select. To make a
   drive the master, attach it to the connector that has the CSEL
   signal line connected to pin 28. To make a drive the slave, attach
   it to the connector that has pin 28 unconnected (CSEL is not
   carried to pin 28 of that cable connector.) Note that CSEL is
   grounded at the host.
