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 devices
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
UATA-100 cable
■
For optimal 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.
■
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. HP has provided extra guide screws installed
in the front of the workstation chassis 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, that device must be
attached to the end (Device 0) connector.
