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

200 to 240 VAC
The SPARC M10 systems are designed to function in an environment with natural
convection airflow.
The following requirements must be followed to meet the environmental specifications.
Ensuring sufficient airflow for the entire system
■
Each chassis is equipped with a cooling function for front-to-rear cooling. Each
chassis has air vents on the front. Exhaust is expelled from the rear of each chassis.
The SPARC M10 systems use internal fans whose airflow reaches the maximum
exhaust airflow shown in
Ensuring that temperature at the intake part of each chassis does not exceed the
