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. 7 5 3 1 +---------+ | o o o o | | o o o o | -------> FRONT +---------+ 8 6 4 2 +---------+ | o o o o | The drive is a master; the slave is either a | o o o o | Medialist family or another ATA-compatible drive, +---------+ there is no slave. +---------+ | o X o o | The drive is master; a slave is present. | o X o o | +---------+ +---------+ | X o o o | The drive is a slave to an ATA-compatible master | X o o o | +---------+ +---------+ | o o X o | Cable select | o o X o | +---------+ 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.
