Configuring the drive

1.Put on a grounded wrist strap. Wear the grounded wrist strap throughout the installation procedure.

2.Install master/slave jumpers. In a two-drive system, you need to designate one drive as the master, or drive 0, and the other drive as the slave, or drive 1. To do this, install the master/slave jumpers as shown in Figure 1. In a one-drive system, configure the drive as a master (no jumpers in- stalled).

Alternatively, you can configure the drive as a master or slave using the cable select option. To use this option, the host system and both drives must support cable select. Cable selection requires a special daisy-chain cable that grounds pin 28 (CSEL) on one of its two drive connectors. If you attach the drive to the grounded CSEL connector, it becomes a master. If you attach the drive to the un- grounded CSEL connector, it becomes a slave.

To configure an ST9655 family drive for cable select, install both master/slave jumpers, as shown in Figure 1.

Attaching cables

This drive is designed for a host computer that supplies interface signals and +5V power through a single 44-pin connector and cable. If your computer has a fixed connector that attaches directly to the drive, skip ahead to the following section, “Mounting the drive.” Otherwise, perform the steps listed on page 4.
