Installation Environment
Sufficient consideration of the installation environment should be taken to ensure proper use of the ETERNUS AX/
HX. Using the ETERNUS AX/HX in an environment that does not satisfy the installation environment requirements
may cause a failure to occur with the ETERNUS AX/HX.
Air Conditioning
It is important to consider the flows of cooling air (intake air and exhaust air) for the installation location of the
ETERNUS AX/HX. The temperature in some ETERNUS AX/HX storage systems may rise by taking in air exhausted
from other storage systems depending on how they are installed near each other. In addition, check if the ambi-
ent temperature in the installation location always satisfies the usage environment temperature by taking into
consideration the room size, whether other storage systems are installed, and how many people are present in
the room.
Take the following points into consideration when installing the air-conditioning system:
●
Ambient Temperature
An ETERNUS AX/HX is cooled by taking in air through the front intakes and pushing out the exhaust air
through the rear of the ETERNUS AX/HX. If the intake air temperature does not meet the ambient environment
conditions, a temperature error occurs and the power of the ETERNUS AX/HX is shut down.
-
Front intake air temperature
Make sure that the front intake air temperature is between 10 and 40 °C.
-
Rear exhaust air temperature
For example, when the intake air temperature is 40 °C, the exhaust air temperature is 50 °C or higher.
The necessary cooling capacity of air conditioning must be determined by taking the exhaust air cooling
into consideration.
Estimate the amount of heat in the exhaust air from the ETERNUS AX/HX by using the heat generation
amount and exhaust air amount that are listed in
