Installing Optional SCSI Devices

Select models of the Compaq Professional Workstation AP200 have an internal SCSI hard drive preinstalled. You can install additional high-performance SCSI devices using the external SCSI connector located on the rear panel of the workstation.

Important Guidelines for Installing

Optional SCSI Devices

If you are installing additional SCSI devices, you must adhere to the following guidelines:

To preserve data integrity, do not install more than 7 SCSI devices per SCSI controller.

The integrated Wide-Ultra SCSI controller requires that a unique SCSI ID (0-7) be set for each SCSI device installed. The controller identifies a SCSI device by its SCSI ID number rather than its location. Moving a SCSI device from one position to another on the SCSI chain does not affect the communication between the controller and the SCSI device. The reserved and available SCSI ID numbers for SCSI devices are as follows:

SCSI ID 0 is reserved for the primary hard drive.

SCSI ID 7 is reserved for the controller.

SCSI IDs 1 through 6 are available.

Every SCSI chain or circuit must be terminated (closed) at both ends. If using a terminated cable, disable the termination for all devices. If using a non-terminated cable, only disable the termination for the last device on the chain.
