Checking Environmental Conditions

This section describes the environmental conditions for the SPARC M10 systems. The
server can be installed at locations that meet the environmental conditions listed in
Table
Note - When designing environmental control systems such as air conditioning facilities,
confirm that the air taken in by each chassis meets the requirements specified in this section.
The environmental conditions described in
chassis. The optimal conditions represent the recommended environment in
operation. The component failure rate may increase substantially when the system
operates for prolonged periods in an environment that is at or close to the operation-
time (in operation) limit values, or when the system is installed in an environment
that is at or close to the non-operation-time (not in operation) limit values. To
minimize the occurrence of system downtime due to a component failure, set the
temperature and humidity within the optimal condition range.
The following conditions must be met to prevent overheating:
Neither warm air nor hot air blows directly on the front of the rack
■
Neither warm air nor hot air blows directly on the front panel of any chassis
