Ultra Wide SCSI Hard Disk Drive and PCI Card
If your computer came with an Ultra Wide SCSI hard disk drive, it includes some or all of the
following components:
m an internal Ultra Wide SCSI hard disk drive
m in certain configurations, additional internal Ultra Wide SCSI hard disk drives
m an Ultra Wide SCSI card in one of your computer’s PCI slots
m an internal Ultra Wide SCSI cable that supports up to three internal devices (including your
pre-installed Ultra Wide hard disks)
Warning Do not connect any SCSI devices to the external 68-pin SCSI-3 connector or
to the internal 50-pin SCSI-2 connector on the PCI card that supports the internal hard
disk. Connecting even one external SCSI device to the external 68-pin connector
extends the overall cable length of the SCSI bus beyond the limit for which error-free
operation can be guaranteed; the combined length of the internal cable and the
external cable reduces the reliability of all the devices connected to the Ultra Wide
SCSI bus. Connecting a device to the internal 50-pin SCSI-2 connector will cause your
Ultra Wide SCSI devices to transfer data at the slower, SCSI-2 rate.
