Connecting Peripheral
Devices
4
Your computer has a number of ports for connecting peripheral devices such as printers,
storage devices, audio equipment, network cabling, and modems.
See ÒPowerWave 604 OverviewÓ on page ix at the beginning of this manual for the location
of the ports.
Using SCSI devices
Your computer has two separate SCSI busesÑone for the internal devices like the hard disk
and the optional CD-ROM drive and another for external devices. You can connect up to
seven devices in a
SCSI chain
to each bus.
Connecting a SCSI device involves four steps:
■
Setting the deviceÕs SCSI ID number
■
Ensuring proper termination
■
Connecting the device
■
Installing a software device driver (if one is required)
Setting the SCSI ID
Each device in a SCSI chain requires a unique number called a SCSI ID, which the computer
uses to identify the device. The computer itself is assigned SCSI ID 7 and the internal hard
disk is assigned SCSI ID 0. Every other device you install must have a unique number from
1 to 6. An optional hard drive is normally assigned a SCSI ID of 1, a tape drive is normally
assigned 2, and a CD-ROM drive or removable-media drive is normally assigned SCSI ID 3.
Devices on the external bus must have a unique SCSI ID from 0 to 6.
The way you assign SCSI IDs varies from device to device. On most external devices, the ID
is displayed on the back of the device. You usually change it by pressing small buttons above
or below the number display. For some external and most internal devices, changing the ID
requires setting switches or moving jumpers. Refer to the documentation that came with the
device for exact instructions.
