Appendix C

Verifying and Troubleshooting SCSI Device
Installation

Use the SCSI Adapters panel to verify that the system recognizes the 
devices you installed.

1.

Select Start > Control Panels.

2.

Double-click the SCSI Adapters icon.

3.

Click the + next to PCI SCSI Card to see a list of installed SCSI 
devices.

If the system does not recognize one or more of the devices:

•

Make sure each device is set to a unique SCSI ID number.

•

Check all the cable connections and verify the last device is 
terminated. Shut down and reboot the system.

•

If the system still does not recognize a device, shut down and 
open up the system. Check to make sure the SCSI PCI card is 
installed correctly (see “Installing a PCI Card” on page 54). If you 
have internal SCSI hard drives installed, make sure the internal 
SCSI cable is securely attached to the drives and to the card (see 
“Attaching the SCSI PCI Option Card Internal Cable” on 
page 51).

Close and reboot the system. If the system still does not recognize the 
device, there may be a problem with one of the devices, one of the 
cables, the terminator, or the PCI card. Contact your support 
representative.
