NOTE:
The setup of the configuration jumpers on the SBC is described below.

* = default value

JU9/JU9A SCSI TERMINATION -
CHANNEL 0
These two jumpers may be used to enable or disable on-board active termination for the Ultra160 SCSI interface on Channel 0.

JU20/JU20A SCSI TERMINATION -
CHANNEL 1
These two jumpers may be used to enable or disable on-board active termination for the Ultra160 SCSI interface on Channel 1.

P100 SCSI ACTIVITY LED ENABLE -
CHANNEL 0
Install to light the hard drive LED for SCSI drive activity on Channel 0. *
Remove if the SCSI controller is not being used.

P101 SCSI ACTIVITY LED ENABLE -
CHANNEL 1
Install to light the hard drive LED for SCSI drive activity on Channel 1. *
Remove if the SCSI controller is not being used.

NOTE:
Pin 1 on the connectors is indicated by the square pad on the PCB.
