I think you missed the point.  Our FE's are trained NOT to have multiple
terminators where they are NOT supposed to be.  That is, if OUR FE's install
one of OUR devices onto an already configured SCSI device system, they
are to make certain that the bus is correctly terminated (that is, terminator
only on the *terminal* device).
