2.4.1 Fair Arb Disable

The large Hub contains a switch on the front panel that allows the user to disable the FAIR ARB feature of the Hub. When FAIR ARB is disabled, the Hub services SCSI arbitration cycles in the conventional SCSI priority order. Host port SCSI ID assignments are not linked to the physical port location in the Hub when FAIR ARB is disabled.
