Air flow
This section describes about air flow direction for cooling the system, and
environmental requirements for shipping and storage.
The following table lists the required environmental conditions during shipping and
storage of the DLm system:
Note:
The air flow direction for cooling the systems should be from front to rear.

Environment acclimation
This section provides an overview of environmental acclimation for a DLm system.
A DLm system requires time to get acclimated to a computer room environment
before and after you unpack it. Before unpacking the unit, allow it to stabilize for 16
hours. After unpacking the unit, do not connect it to AC power for at least the number
of hours specified in the following table.
The following table lists the environmental acclimation:
