Serial ATA Jumpers and cabling

by Mystic Overclocker
2003/05/03

Serial ATA drives are designed for easy installation with no jumpers, terminators, or other settings. It is not necessary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector is for factory use only.

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. Each drive has its own cable.

Your serial ATA host adapter may provide master/slave emulation options. See your host adapter documentation for details.

Once you get power and data to the hard drive, the next step is to connect it to the motherboard. The edge connector is keyed, so you can't install it the wrong way. If you examine a motherboard connector (note the white blocks at lower-left side of image), you'll see the L-shaped key on one side of the connector.

Plugging the cable connector into the motherboard connection is literally a snap -- certainly easier than trying to line up and push down that pesky parallel ATA cable. Once in, the connector and cable take up very little room.
