  I would like to know if anyone has experienced "selftest failure" problems
  with their DEC LANbridge 200s. I have 12 of these units (6 fiber and 6 local),
  and all of them exhibit the same problem. The older units I got when DEC was
  offering to upgrade 100s and 150s to 200s (Sept 1990). These models have ROM
  and software revs @ 1.2 and hardware rev 25.7. The newer units (Oct 1991) are
  at 1.6 and 25.8. 

  All of these bridges show "selftest failure" at the main status screen and
  "possible external fault" and the line status screens. All fiber has been shot
  with a OTDR, and the distance and loss budgets are well within specs. Small
  test nets have been set up to make sure that there are no configuration
  problems with the local bridges.

  DEC's hardware folks were made aware of this as soon as the problem was found
  (day one), and hoped that a ROM upgrade would help. Ver 1.5 was supposed to 
  be the fix, but it was in Beta and was not to be released. Needless to say
  Ver 1.6 didn't help.  

  I don't want you DEC guys to get me wrong...I'm not raggin' on you!!!

  Anyone else seen this problem? 

  Can't very well define an alarm rule for "device broken" when it always is...
  although the bridges work fine.
 
  Thanks!!
