Place that is close to some equipment that causes power noises (e.g., sparks caused by
power-on/off using a relay). If you must install the server close to such equipment, request
your sales agent for separate power cabling or noise filter installation.
IMPORTANT:
Temperature increase inside the rack and airflow
If you install several components or the ventilation isn't good inside the rack, the internal
temperature may increase due to heat emitted from the components. When the operating
temperatures of NEC Express5800/ft series (10 to 35°C) are exceeded, there is a risk of
malfunction. You must take adequate precautions and measures for airflow inside the rack as well
as in the room so that the internal temperature can be kept within this range during operation.
