Guidelines for Using SCSI Devices

When installing and operating SCSI devices, follow these guidelines:

■A single Ultra SCSI controller supports up to seven SCSI devices per channel.

■Each Wide-Ultra SCSI, Ultra-Wide SCSI, Wide Ultra2 SCSI, Ultra 320 SCSI, or Ultra 160 SCSI controller supports up to 15 SCSI devices per channel.

■If you are using multiple SCSI devices, Compaq recommends that the devices be split between Channel A and Channel B, if available, for optimum performance.

■Compaq recommends the following SCSI cable:

❏53 inches maximum length twisted-pair, LVD cable with built-in terminator, maximum of 5 drives with a minimum drive spacing of 5.25 inches

■The SCSI controller requires a unique SCSI ID (0-7 or 8-15) for each SCSI device installed. The controller identifies a SCSI device by its SCSI ID number rather than by its location. Moving a SCSI device from one position to another on the SCSI chain does not affect communication between the controller and the device. The reserved and available SCSI ID numbers for SCSI devices are:

❏0—reserved for the primary hard drive

❏7—reserved for the controller

❏1 through 6 and 8 through 15—available for all other SCSI devices

■Either a CD-ROM or DVD-ROM is shipped in bay 4.
