Ultra Ata Jumpers; Ultra Ata Cables; Drive Installation Guidelines - HP xw4200 Service And Technical Reference Manual

Ultra ATA Jumpers

Ultra ATA drives are configured with jumper settings. With cable-select, the drive is configured as either
Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.
If you purchase a third-party hard drive, refer to the documentation included with the drive kit to ensure
proper cable installation and configuration.
NOTE All drives on a controller channel need to have their jumpers either in the cable-select mode or
have the individual drive jumper installed on the appropriate Master (Drive/Device 0) or Slave (Drive/
Device 1) position.

Ultra ATA Cables

When installing a second device on the primary 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 higher data transfer rates possible with the improved
technology.
When using Ultra ATA-133, -100, -66, and slower -33 drives in the same system, each drive will operate
at its appropriate data transfer rate.
NOTE On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system
board connector and the Drive/Device 1 connector is always the closest to the system board connector.
NOTE Some cables might be labeled "Drive 0" instead of "Device 0" and "Drive 1" instead of "Device 1."

Drive Installation Guidelines

The HP Workstation xw4200 system board has one Ultra ATA (IDE) controller channel designated as the
primary controller.
The controller can have up to two devices attached to it, and all drives are connected to this controller
using an industry-standard, 80-conductor cable.
NOTE The industry-standard, 1.44-MB diskette drive has its own separate channel and is not included
as a part of the maximum four drives.
Any drive attached to a controller must have a drive designation. If only a single drive is connected to a
controller and its jumper is in the cable-select position, it is designated as the Master Drive (Drive/Device
0) by its attachment to the Drive/Device 0 cable position. If two cable-selected drives are connected to a
single controller, one will be designated by its attachment to the cable as the master (Drive/Device 0) and
the other as slave (Drive/Device 1).
