SCSI IDs
By default, specific devices use the following SCSI IDs:
♦
System disk drive (standard) uses ID 0
♦
SCSI controller uses ID 7
NOTE
To easily determine the ID of each SCSI device on the system, restart the system.
When the BIOS screen displays, look for the list of SCSI devices and write down the
ID for each device.
Some SCSI devices feature push switches to set the ID, while others have DIP switches or
jumpers. See the vendor documentation for details on setting the ID.
Connecting External SCSI Devices
To connect external SCSI devices:
1.
If the system is connected to AC power and operating, shut down the system and unplug the
system power cord from its AC power outlet.
2.
Connect one end of a SCSI cable to the SCSI port on the system.
3.
Connect the other end of the SCSI cable to a SCSI peripheral device.
4.
Connect a SCSI cable between SCSI ports on any additional SCSI peripheral devices.
5.
Set the SCSI ID of each peripheral device to a unique SCSI ID number. Do not use any SCSI
ID numbers already used by the system.
6.
For each SCSI peripheral device connected to the port, if the device is:
−
The last or only device on the SCSI chain, enable SCSI termination
−
Not the last or only device on the SCSI chain, disable or remove SCSI termination
7.
Ensure that the power switch on each peripheral device is in the off position; then connect the
power cord from each peripheral device to an AC power outlet.
8.
Turn on power to all connected SCSI peripheral devices, and then start the system.
9.
If necessary, install software drivers and configure the peripheral devices according to the
vendor’s instructions.
Most SCSI controllers do not recognize a hard disk drive formatted using a different brand of
controller. You must use Symbios-formatted hard disk drives with a Symbios SCSI controller.
If you want to boot the system from an external SCSI hard disk drive, ensure the SCSI controller to
which the boot drive is connected is installed lower in slot order than all other bootable SCSI
controllers and devices.
