Replacing the Integrated SCSI Controller
Use the following guidelines if you are replacing the integrated SCSI
controller with the 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter:
17. Unplug the original SCSI cable from the system board.
18. Plug the SCSI cable into the appropriate connector on the 64-Bit/66
MHz Single Channel Wide Ultra3 SCSI Adapter.
IMPORTANT:
There are two main restrictions on connecting SCSI devices to this
controller.
■
Connectors J1 and J3 can be used for either LVD or SE SCSI devices. However,
connecting an SE device will cause any LVD devices attached to the same controller
to slow down to SE speeds.
■
Connectors J4 and J5 can only be used for SE devices. These two connectors
cannot be used simultaneously.
For more information on connecting cables, see “Cabling the 64-Bit/66
MHz Single Channel Wide Ultra3 SCSI Adapter,” earlier in this chapter.
19. Depending on your server model, you may need to secure the cable by
clipping it to another component in the server. Refer to your system
documentation for specific instructions on internal cabling.
The 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter now supports
the internal SCSI devices. The integrated controller on the system board can
be used to support other SCSI devices. If you are not using the integrated
controller to support other SCSI devices, it must be terminated.
Proceed to “Completing the Installation,” later in this chapter.
Connecting Additional Internal SCSI Devices
Use the following guidelines to connect new SCSI devices to the 64-Bit/66
MHz Single Channel Wide Ultra3 SCSI Adapter. To perform this procedure,
you will need to order an additional SCSI cable appropriate for each type of
device you are connecting to the 64-Bit/66 MHz Single Channel Wide Ultra3
SCSI Adapter. See “SCSI Cables” in Chapter 1 for information on ordering
the correct cable for your server model.
1. Install the additional SCSI device(s) in the server. Refer to the
documentation provided with your system for specific installation
instructions.
2. Plug the new cable(s) into the appropriate connector(s) on the 64-Bit/66
MHz Single Channel Wide Ultra3 SCSI Adapter.
