Each intelligent drive in your system requires a separate
interface cable. The WDXT-140 and the WDXT-150 DO NOT
support hard disk drives attached to daisy chain cables.

configure and to install your intelligent drive(s). These steps may

include:

• setting the drive number and terminator resistor

• attaching the cable(s) to each drive

• mounting the drive(s) into the computer case

• attaching your drive to a power source
