Guidelines for Installing Ultra ATA Devices

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.

■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.
