HP Single Channel Ultra320 SCSI G2 Host Bus Adapter - Manual (Page 17)

Installing the Hardware
Internal SCSI Connections
Use the information in this section to connect the Single Channel Ultra320 SCSI HBA G2 to
internal SCSI devices. The most common cabling scenarios include:
•
Placing hard drives or other devices on a separate SCSI bus
•
Replacing the integrated SCSI controller with Single Channel Ultra320 SCSI HBA G2
•
Connecting additional internal SCSI devices
CAUTION: If the server has an integrated Ultra320 SCSI controller, the controller must be
terminated at all times to prevent boot error messages.
IMPORTANT: To run in LVD mode (Ultra320 or Ultra160), all components, including the ribbon cable,
must be LVD capable.
Replacing the Integrated SCSI Controller
Use the following guidelines to replace the integrated SCSI controller with the Single
Channel Ultra320 SCSI HBA G2:
1. Unplug the original SCSI cable from the system board.
2. Plug the SCSI cable into the appropriate connector on the Single Channel Ultra320 SCSI
HBA G2.
IMPORTANT: Do not connect SCSI cables to both internal and external connectors from the same
port. If both SE and LVD devices are in the server, use a separate port for each.
For more information on connecting cables, refer to “Cabling the Single Channel
Ultra320 SCSI HBA G2” in this chapter.
3. Depending on the server model, the cable might need to be secured by clipping it to
another component in the server. Refer to the system documentation for specific
instructions on internal cabling.
The Single Channel Ultra320 SCSI HBA G2 now supports the internal SCSI devices. The
integrated controller on the system board can be used to support other SCSI devices. If the
integrated controller is not being used to support other SCSI devices, it must be terminated.
Proceed to “Completing the Installation” in this chapter.
