Technical Information 1-19
SCSI-1, SCSI-2, SCSI-3, and Wide UltraSCSI device protocol
Advanced SCSI features including multi-threaded I/O (up to 255 tasks
simultaneously), scatter/gather, tagged command queuing, disconnect/reconnect,
and synchronous and asynchronous data transfer
Extended translation scheme supports up to eight GB per disk
Drivers may be single-ended, active, or programmable via the SCSISelect
configuration utility.
DISKETTE DRIVE
Up to two diskette drives are supported in the system. The installed 3 1/2-inch diskette
drive is connected by a single ribbon cable with two drive connectors. The diskette drive
cable plugs directly into the system board. Typically, there are no switches or jumpers that
need to be set, both diskette drives are terminated, and the cable determines drive A and B.
Connector locations are given in Appendix A.
HARD DISK DRIVE
Up to four IDE hard drives are supported in the system (non-SCSI configurations). In the
SCSI configuration, up to 15 SCSI devices (disk drives, CD-ROM drives, scanners, tape
backups) are supported by the Ultra Wide SCSI adapter board. Two SCSI devices can be
installed internally in the system chassis.
IDE Hard Drives
The system board has two IDE/PCI interface connectors (primary and secondary) for
connecting IDE storage devices such as hard disk drives. Each connector supports up to
two IDE devices. Connector locations are given in Appendix A.
All systems ship with one internal 3 1/2-inch hard disk (1-inch high, thin-height) installed
behind the front panel in the bottom slot in the drive cage. The three-connector hard disk
drive cable plugs into the primary connector on the system board. An optional second hard
drive can be connected to the middle connector on the primary IDE cable. A third hard
drive (in a 5 1/4-inch accessible slot) can be connected to the middle connector on the
secondary IDE cable.
NOTE:
The first connector on the secondary
IDE cable connects the standard CD-ROM
reader to the system board.
The standard hard disk drive is set as the master device on the primary IDE/PCI port (see
Figure 1-3 for jumper settings). Use the Storage Device Installation procedures in Section 3
when installing optional devices.
