Checking Cooling Conditions

This section describes the cooling conditions for the SPARC M10 systems. Note the
following conditions when installing the system:
The air conditioning facilities for the room are sufficient to meet the cooling
■
conditions of the entire system
The air conditioning facilities have control functions for preventing excessive
■
temperature changes
