Guidelines for Installing Ultra ATA Devices

B–2
When installing additional Ultra ATA drives, follow these guidelines:
■
If using multiple Ultra ATA devices, split the 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.
■
Use an 80-conductor Ultra ATA cable:
❏
18 inches maximum total length, 80-conductor cable with
maximum spacing of 6 inches between Device 0 and
Device 1.

■
For optimal performance, connect hard drives to the primary
controller. Connect expansion devices, such as ATA CD-ROM
and DVD-ROM drives, tape drives, and diskette drives, to the
secondary controller.
■
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. Extra guide screws can be found behind the front
bezel. Some options use M3 metric hardware. HP supplied metric
screws are black.
■
If only one device is connected to a cable, attach that device to the
end (Device 0) connector.
