Ventilation; Server Front Panel - Hitachi 3080 G2 Hardware Reference Manual

Ventilation

There are vents and fan openings on the front and the rear of the server.
These openings are designed to allow airflow, which prevents the server from
overheating.
Note: At least four inches of clearance must be present at the rear of the
server rack so that airflow is unrestricted.
Caution: Do not place the server in a built-in installation unless proper
ventilation is provided.
Do not operate the server in a cabinet whose internal ambient temperature
exceeds 35º C (95º F).
