3. Check the Card’s Hardware Configuration

Hardware settings for the SCSI/parallel adapter apply to the SCSIport only. There are no hardware settings for the parallel port. Figure 1-3showsthe applicablehardware. To check the card’s hardware, perform the following:

1.Setthe desired parity-checking capability.

2.Set the SCSI bus address.

3.Verify that resistor packs are properly installed.

The SCSI/parallel adapter contains switchesfor settingthe parity-checkingcapability and the SCSI bus addressof the card. The default switch settingsare “allswitchesopen”, rcsllting in:

nparity-checking is enabled, and

=SCSI bus address is 7.

In addition, the card contains resistor packsfor terminating oneend of the SCSIbus.
