i think this is a spurious error.  if you start getting a bunch of them it might be
indicative of a failing/ed sensor which needs to get replaced.  i also get these
every now and then on our 2450s.

yes, you have to hunt through the interface (i can't remember exactly where)  but
there is a "clear lights" option somewhere there which fixes this.  sometimes the
esm seems to get confused which can cause this and all you have to do is clear it.

you want to make absolutely sure there is no problem though (e.g failed drive or
fan etc)
