Ultra ATA Drive Guidelines and Features
4.1 Ultra ATA Jumpers
Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with
the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on
factory pre installed, replacement, or option drives. With cable-select, the drive is configured as
either Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.
If you purchase a third-party hard drive, refer to the documentation included with the drive kit to
ensure proper cable installation and configuration.
✎
All drives on a controller channel need to have their jumpers either in the cable-select mode or
have the individual drive jumper installed on the appropriate Master (Drive/Device 0) or Slave
(Drive/Device 1) position.
4.2 Ultra ATA Cables
When installing a second device on either the primary or secondary controller, you must use an
industry standard 40-pin, 80-conductor Ultra ATA cable for optimal performance. These cables
have a maximum length of 18 inches and a maximum distance of 6 inches between the two
devices for a two-drive cable.
Drives operating at speeds faster than those of the Ultra ATA-33 devices require industry-
standard 40-pin, 80-conductor cables to maintain the higher data transfer rates possible with the
improved technology.
When using Ultra ATA-133, -100, -66, and slower -33 drives in the same system, each drive will
operate at its appropriate data transfer rate.
4.2.1 Cable Layout
The faces of industry-standard cable connectors are color coded for easy recognition:
■ System board connector = blue face
■ Device 0 connector = black face
■ Device 1 connector = gray face
✎
The color code of an industry-standard cable is valid only if the drive’s jumper is in the cable-
select position.
