Guidelines for Installing Ultra ATA Devices

B-2
When installing additional Ultra ATA drives, follow these
guidelines:
If using multiple Ultra ATA devices, Compaq 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(s) to the
system board.
UATA-100 cable:
18 inches maximum total length, 80-conductor cable with
maximum spacing of 6 inches between Drive 0 and Drive 1.

2 Device 1 (secondary drive) connector
3 System board connector
For optimum performance, connect hard drives to the primary
controller. Connect expansion devices, such as Ultra ATA
CD-ROM drives, tape drives, and diskette drives, to the
secondary controller (white connector on Evo Workstation
W8000).
Install either a third-height or a half-height drive into a half-
height bay.
Install guide screws to ensure that the drive lines up correctly in
the drive cage. Compaq has provided extra guide screws
installed in the front of the workstation chassis behind the front
bezel. Some options use M3 metric hardware. Compaq-supplied
metric screws are black.
If only one device is connected to a cable, that device must be
attached to the end (Device 0) connector.
