Configuring the drive

Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host

adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point

relationships. If two drives are attached on one Serial ATA host adapter, the host operating system views the

two devices as if they were both “masters” on two separate ports. This means both drives behave as if they are

Device 0 (master) devices.

Serial ATA drives are designed for easy installation. It is normally not necessary to set any jumpers on this

drive for proper operation. If the host system does not support SATA 3Gb/s operation, place a jumper on pins 1

and 2 to limit the drive to 1.5Gb/s operation.

Serial ATA cables and connectors

The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-

tions. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 9

for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.

For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive

and the host receptacle incorporate features that enable the direct connection to be hot pluggable and blind

mateable.

For installations which require cables, you can connect the drive as illustrated in Figure 3.

Each cable is keyed to ensure correct orientation.
