Set conditions to the optimal temperature and humidity ranges to minimize the
chance of downtime due to component failure. Operating the Sun Server X4-2 for
extended periods at or near the operating range limits, or installing it in an
environment when it remains at or near nonoperating range limits could significantly
increase hardware component failure. See also:
