Operating Environment - Sun Microsystems Sun Fire V215 Getting Started Manual

Operating Environment

Your environmental control system must provide intake air for the server that
complies with the limits specified in
To avoid overheating, do not direct warmed air:
Toward the front of the cabinet or rack.
■
Toward the server access panels.
■
Note – When you receive your system, leave it in the environment in which you
will install it for 24 hours. This helps prevent thermal shock and condensation.
The operating environmental limits in
have been tested to meet all functional requirements. Operating computer
equipment in extremes of temperature or humidity increases the failure rate of
hardware components. To minimize the chance of component failure, use the server
within the optimal temperature and humidity ranges.
Ambient Temperature
An ambient temperature range of 21˚ C to 23˚ C is optimal for server reliability. At
22˚ C it is easy to maintain safe relative humidity levels. Operating in this
temperature range provides a buffer in the event of the environmental support
systems failing.
Ambient Relative Humidity
Ambient relative humidity levels between 45% and 50% are the most suitable for
data processing operations to:
Prevent corrosion.
■
Provide an operating time buffer in the event of environmental control system
■
failure.
Help avoid failures caused by the intermittent interference from static discharges
■
that occur when relative humidity is too low.
Electrostatic discharge (ESD) is easily generated and less easily dissipated in areas
where the relative humidity is below 35%, and it becomes critical when levels drop
below 30%.
