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.
SCSI Termination Guidelines for External Devices
Follow the guidelines below for terminating SCSI devices:
Enable termination on the last external drive on the SCSI cable chain.
Disable termination on all other external drives on the SCSI cable chain.
Use only an active terminator on externally-terminated devices.
Connecting the Device
To add an external SCSI device:
1. Connect one end of the external SCSI cable to one of the following external ports:
−
The integrated Narrow Ultra SCSI port
−
The integrated Wide Ultra2 SCSI port
2. Connect the other end of the cable to the SCSI device.
3. Set the SCSI ID of the device to an unused number.
4. If the SCSI 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 SCSI termination
5. Ensure that the power switch on the device is in the off position, and then connect the
power cord to the device and then to an AC receptacle.
6. Turn on the power to the device and any other devices on the SCSI chain.
7. Start the system. If necessary, install the software drivers and configure the drive
according to the vendor’s instructions.
Changing SCSI Host Adapter or Device Settings
Depending on your system configuration or the capabilities of SCSI devices connected to your
system, you may need to use the SCSI Configuration Utility to change host adapter or device
settings. See the System Setup for details.
