   The backplane is third-party, not DEC, and has
integral 
termination (no terminator card per se.)  It has 8 quad-height slots.

  Question: Is the RLV11 appropriate and if so, which
slots do they 
go in? 
Not appropriate - you have no CD slots at all in this backplane.  It
looks like it's either a serpentine or zig-zag ABAB layout.

Is this a Sigma box/backplane, by any chance?  If so, it probably
has a big yellow warning sticker inside telling you that if you plug
in anything that expects to use the CD slots for its own purposes,
you'll end up letting the magic smoke out (or something to that
effect.)

Move the cards to a more conventional DEC backplane and you
can probably use the RLV11 just fine.  Alternatively you could
just go out and spend the bucks for a RLV12 (they were only about
$150 a few years back.)
