When installing additional drives, follow these guidelines:

■For optimal performance, connect hard drives to the primary controller. Connect expansion devices, such as CD-ROM, IDE tape, and diskette drives to the secondary controller.

Refer to Chapter 4 for more detailed information on Ultra ATA drives and to Chapter 5 for SCSI drives.

■You must install guide screws to ensure that the drive lines up correctly in the drive cage. Extra guide screws are provided that are installed in the front of the computer chassis behind the front bezel. Some options require metric hardware. Factory-supplied metric screws are black.

■Drive installation requires no jumper setting changes on the existing or optional drives. All factory-installed drives have the jumpers preset for cable-select installation.

■The system automatically recognizes hard drives any Plug and Play hard drive and will automatically reconfigure the computer. If you installed a hard drive that is not a Plug and Play device, you must run Computer Setup to reconfigure the computer.

If installing a second device on the primary controller, you must use an 80-conductor Ultra ATA cable for optimal performance. This cable is available as an HP option.

ÄCAUTION: When servicing the computer, ensure that cables are placed in their proper locations during the reassembly process. Improper cable placement can damage the computer.
