Hello

I was slightly bemused by the description of your system, is it a 927LX
or is it a 950, or have I misunderstood and you have two HP3000's and
they both went overtempature.

Your reference to MPE 3.0 makes me think you have one of the original PA
M/C's which were real gas guzzlers (read heat generators) as were the
disc drives for it.

Assuming that it is an old 950 and the HP-UX m/c may be of a newer
generation I think it quite likely that the 3000 went down sooner and
stayed down longer.

I don't know what the published temperature range was for the 950, but
for a 928LX the operating temperature range is +5C (41F) to +40C (104F),
whilst it's non operating temperature (ie safe to store but not to
operate goes up to 65C (i.e. To Hot To Handle). By the way the advised
temperature rande for tape media is only up to 45C above which it is
likely to degrade. So if your computer room got any hotter than this and
you keep any tapes in it, don't rely on them anymore.

Personally if you have an old 950 and discs, I'm sure someone can do you
a cost analysis that would prove that swopping it for a 928 would have a
very early payback, in saved electricity costs, maintenance costs, as
well as being an awfull lot faster.

Anyway to sum up, I think somewhere under 40C (104f) is the temperature
that your 950 will go belly up.
