Pull the chassis out of any wrapper (pedestal, etc) With the side cover 
plate over the front off (this would give top access to the drives/tape) 
look at the harness that connects the PSU to the back plane. If the RED and 
BLACK wires are all equal lengthed then you have the updated wiring 
harness. If the harness lays flat because the wires closer to the edge of 
the back plane are shorter than those at the end, then you have the 
"catches fire" wiring harness. The shorter power leads carry more current 
and the harness gets hot enough to ignite the insulation of the wires.

There is a field note on it somewhere and you used to be able to call 
1-800-DIGITAL and get a free harness but these days who knows. Now I just 
keep BA23's with the harness and toss the "bad" ones.
