SCSI Bus Interface Definitions
■
Host Adapter SCSI ID —Sets the SCSI ID for the SCSI card.
The SCSI Card 2906 is set at ID 7, which gives it the highest pri-
ority on the SCSI bus. You should not change this setting.
■
SCSI Parity Checking —When set to Enabled, verifies the
accuracy of data transfer on the SCSI bus. Leave this setting
enabled unless any SCSI device connected to the SCSI card
does not support SCSI parity. If one SCSI device does not sup-
port SCSI parity, set parity on the 2906 to Disabled.
■
Host Adapter SCSI Termination —Determines the termination
setting for the SCSI card. The default setting is Automatic,
which determines termination as follows:
– If a cable is only connected to the SCSI card’s internal or
external SCSI connector, the terminators are enabled, if the
2906 termination is set for automatic. (The SCSI card is at the
end
of the SCSI bus.)
– If a cable is connected to the SCSI card’s internal and
external SCSI connector, the terminators are disabled. (The
SCSI card lies between the ends of the SCSI bus.) You can also
disable the terminators by setting Host Adapter
Termination
in SCSISelect to Disable.
You should leave this setting at Automatic.
Note:
The option is for terminating the SCSI card, not for ter-
minating devices. Be sure that both ends of the SCSI bus are
terminated (see the SCSI Card 2906 Installation Guide for
details).
