1-34 Technical Information
Channel A SCSI Bus Termination
Terminate the extreme ends of the SCSI bus (cable), typically by connecting a terminated
device to the end connectors of the cable:
On the last connector of the internal cable (farthest from the system board), attach
either a terminated 16-bit device or some other type of 16-bit termination.
If the internal cable ends at the system board, enable system board termination in
the SCSI BIOS (on bootup, press
Ctrl A
to enter the SCSISelect
utility).
If the internal cable does not end at the system board, but continues on to the
external termination card, disable system board termination in the SCSI BIOS
(using the SCSISelect utility).
If an external SCSI cable is attached to the terminator card, the terminator card’s
termination is disabled automatically. On the last connector of the external cable,
attach either a terminated 16-bit device or some other type of 16-bit termination.
When using 16-bit SCSI devices on channel A:
Use the onboard 68-pin Wide connector for cabling to 16-bit devices.
Enable termination only on the last device on the SCSI cable (internal and/or
external).
Remove or disable termination on all other devices.
Channel B SCSI Bus Termination
Terminate the extreme ends of the SCSI bus (cable), typically by connecting a terminated
device to the end connectors of the cable:
On the last connector of the internal cable (farthest from the system board), attach
either a terminated 16-bit device or some other type of 16-bit termination.
If the internal cable ends at the system board, enable system board termination in
the SCSI BIOS (on bootup, press
Ctrl A
to enter the SCSISelect
utility).
If the internal cable does not end at the system board, but continues on to the
external termination card, disable system board termination in the SCSI BIOS
(using the SCSISelect utility).
If an external SCSI cable is attached to the terminator card, the termination card’s
termination is disabled automatically. On the last connector of the external cable,
attach either a terminated 16-bit device or some other type of 16-bit termination.
