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.
