Installing the Compaq 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter 2-5
CAUTION: If your server has an integrated Wide Ultra3 SCSI controller, the
controller must be terminated at all times to prevent boot error messages.
IMPORTANT: In order to run in LVD mode (Wide Ultra3), all components, including the
ribbon cable, must be LVD-capable
Placing Hard Drives or Other Devices on a
Separate SCSI Bus
Use the following guidelines if you are using 64-Bit/66 MHz Single Channel
Wide Ultra3 SCSI Adapter to provide a separate SCSI bus for one or more
devices in the server.
To add a separate SCSI bus, you may need an internal SCSI cable designed
specifically for your server model. Refer to the documentation that came with
your server to determine if you need an additional cable. If the cable was not
provided with your system, you can obtain it from your local Compaq
Reseller. See "SCSI Cables" in Chapter 1 for information on ordering the
correct cable for your product.
13. Remove any devices from the existing SCSI bus that you want to move
to the new SCSI bus.
14. Install any new SCSI devices.
15. Locate the new SCSI cable. Plug one end of the cable into the
appropriate connector on the 64-Bit/66 MHz Single Channel Wide
Ultra3 SCSI Adapter.
IMPORTANT: Do not connect SCSI cables to both internal and external connectors from
the same port. If you have both SE and LVD devices in your server, use a separate port for
each.
For more information on connecting cables, see "Cabling the 64-Bit/66
MHz Single Channel Wide Ultra3 SCSI Adapter," earlier in this chapter.
16. Attach one or more device connectors on the cable to the SCSI device(s)
or backplane connector.
Proceed to "Completing the Installation," later in this chapter.
