2.5 Installation Environment
Sufficient consideration of the installation environment should be taken to ensure proper use of the ETERNUS
DX Disk storage system. Using the ETERNUS DX Disk storage system in an environment that does not satisfy
the installation environment requirements may cause a failure to occur with the ETERNUS DX Disk storage
system.

2.5.1 Air Conditioning

It is important to consider the flows of cooling air (intake air) and exhaust air for the installation location. The
temperature in some ETERNUS DX Disk storage systems may rise when exhaust air is taken in from other
ETERNUS DX Disk storage systems. In addition, check other factors that might affect the usage environment
temperature, such as the room size, whether other ETERNUS DX Disk storage systems are installed, and how
many people are present in the room.
When installing air conditioning, the ambient temperature should be considered.
