you void the warranty. Seagate customer service centers are the
only facilities authorized to repair Seagate drives. Seagate does
not sanction any third-party repair facilities.

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.
