Backplane Fail This parameter specifies the number of
successive transfer errors that must
occur before the communication ports
are shut down. If the parameter is set to
0, the communication ports will continue
to operate under all conditions. If the
value is set larger than 0 (1 to 65535),
communications will cease if the
specified number of failures occur.
