Hard Drive Installation Guidelines
Using the Cable-Select Feature with Ultra ATA
Devices
Optional drives and optional drive cables are available from HP in kits. The
configuration of the drive employs a cable-select feature that identifies the drive as
device 0 (primary drive) or device 1 (secondary drive).
Device 1 is the drive connected to the middle cable connector. Device 0 is the drive
connected to the end cable connector (applies only to 80-conductor ATA cables). See

"Guidelines for Installing Ultra ATA Devices"

Ultra ATA cable.
HP hard drives ship with jumpers preset to cable-select mode; therefore, no jumper
setting changes on the existing or optional drives are required. If you purchase a
third-party hard drive, refer to the documentation included with the kit to ensure
proper installation and configuration of cables.
If installing a second device on the primary controller, you must use an 80-conductor
Ultra ATA cable for optimal performance. This cable is standard on select models.
Guidelines for Installing Ultra ATA Devices
When installing additional Ultra ATA drives, follow these guidelines:
If using multiple Ultra ATA devices, HP recommends that the devices be split
between the primary and secondary Ultra ATA channels for optimum
performance. Use an additional Ultra ATA cable to connect the additional device
to the system board.
