1An external terminator might be required on the adapter, depending on the SCSI bus configuration. If you need an external terminator for the A6828A, use SCSI LVD/SE terminator (HP product number C2370A).
Using the Jumper for Controlling Auto Termination
The A6828A adapter has one set of pins that control enabling and disabling of the auto termination feature. The
The default setting of the pin set on the A6828A HBA is the open position (the jumper is on only one pin of its pin set). This is the auto termination enabled state. In this state, the A6828A automatically senses whether a cable from a powered SCSI device is attached and provides the proper termination (depending on whether a powered device is present).
To disable auto termination on the adapter, change the jumper from the default open position to the shorted position (the jumper is on both pins of the pin set). This is the auto termination disabled state.
