Recommended 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:
Towards the front of the cabinet or rack
■
Towards 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 is to 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 system 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.
