Connecting an External SCSI Device
The optional SCSI adapter card is designed to support Ultra Wide SCSI devices. Ultra Wide SCSI
provides a maximum data transfer rate of 80 MB per second. If you connect a non-Ultra Wide
SCSI device to the adapter, data transfer rates are limited to the speed of that device.
CAUTION
Using a non-compliant SCSI-1 device with your system may cause your system to
stop working or lead to other unpredictable results.
You can connect up to seven external single-ended SCSI devices to the SCSI adapter. However,
the number of drives and length of the cables used to connect the drives is a factor when using
SCSI-1, Fast SCSI (SCSI-2), Ultra SCSI, and Wide Ultra SCSI drives. Fast SCSI, Ultra SCSI,
Wide Ultra SCSI, and LVDS impose shorter cable restrictions than SCSI-1.
NOTE
Make sure the last device on a chain of external SCSI devices has an active SCSI
terminator connected to the open SCSI port. All other external SCSI devices must
have SCSI termination disabled or removed.
See the System Reference and the SCSI adapter documentation for more detailed information on
the SCSI adapter and connecting SCSI devices to it.
