3 drives on a KFQSA?

Has anyone successfully run three DSSI disk drives on a KFQSA? I've tried
several times to configure mine to do that but it keeps coming up bogusly.

The only "odd" bit is that one of my drives is _not_ connected to the
control panel (you know the protect/enable/etc) panel. I am beginning to
suspect I need to understand what the three switches that are on all RF
series drives actually do.

I can get two to appear, but not the third.

Configuration:
                     ** **
          RF72 RF71 RF71
        (UNIT=2) (UNIT=1) (UNIT=0)
*TERM*-----+--------+---------+-------> KFQSA (id 6)

KFQSA has three "nodes" (0, 1, and 2)
        776450 - 0
        760334 - 1
        760340 - 2

UNIT 1 and UNIT 0 are connected to the control panel, with ID plugs 0 and
1. UNIT 2 is not connected to the control panel (no cable nor ID plug)

With three disks defined on the KFQSA I get one to show up (usually UNIT 2
as DUA2). With two defined I get DUA2 and DUB0. If I disconnect the RF72 I
get DUA0 and DUB1.

Questions:
        What do the switches on the drives do?!?
        Has anyone configured three disks on one of these things?
