	Enable termination on a SCSI channel if the controller is installed at one end of that channel. This setting terminates the channel and power s its SCSI TERMPWR signal. Disable termination on a SCSI channel if the controller is not at the end of that channel (both external and internal devices exist on the same channel).

DIAGNOSTIC LED(S)
LED	Status	Condition
JP5/pins 1 & 2	On	SCSI is active (Data is being transmitted/received across SCSI channels)
JP5/pins 1 & 2	Off	No SCSI activity
JP5/pins 3 & 4	On	PCI is active (Data is being transmitted/received to/from host)
JP5/pins 3 & 4	Off	No PCI activity
JP5/pins 5 & 6	On	Write is pending (Cache holds data that needs to be written to disk)
JP5/pins 5 & 6	Off	No write is pending
Note: If the system loses power or is reset while JP6/pins 5 & 6 are on, the data in cache memory will be lost. Install the optional cache batter backup module J2 to avoid data loss.
