2.7 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
Table 2-9 lists the cooling conditions for each chassis.
