Ultra ATA jumpers NOTE This system supports a mixed configuration of UATA/IDE optical drives, and SAS and SATA hard drives. While HP supports the presence of SCSI and IDE hard drives, it does not ship any configurations using those drives. Ultra ATA drives are configured with jumper settings.
Ultra ATA cables When installing a second device on either the primary or secondary controller, you must use an industry standard 80-conductor Ultra ATA cable for optimal performance. These cables have a maximum length of 18 inches and a maximum distance of six inches between the two devices for a two-drive cable. Drives operating at speeds faster than those of the Ultra ATA-33 devices require industry-standard 40- pin, 80-conductor cables to maintain the highest data transfer rates possible with the improved technology.
Drive installation guidelines Most workstation system boards have two ATA (IDE) controller channels with a dedicated connector for each controller. One controller is designated as the primary and the other as the secondary controller. Each of the two controllers can have up to two devices attached to it. Each workstation system might therefore have a maximum of four ATA/ATAPI drives.
Primary Controller* Installing drive order *If there are three or more devices, two or more of which are hard drives, two hard drives should be attached to the primary controller first before following the general attach sequence rule. The attach sequence rule can also be stated in table format: Table C-2 General attach sequence rule Sequence...
