Rack-Mounting the System
The following explanations should be noticed when installing the system into the 19-inch rack.
y Install the system in an open rack whenever possible. If installation in an enclosed rack is
unavoidable, ensure that the rack has adequate ventilation.
y Maintain ambient airflow to ensure normal operation. If the airflow is blocked or restricted,
or if the intake air is too warm, an over temperature condition can occur.
y Avoid placing the system in an overly congested rack or directly next to another equipment
rack. Heat exhaust from other equipment can enter the inlet air vents and cause an over
temperature condition.
y Equipment near the bottom of a rack might generate excessive heat that is drawn upward
and into the intake ports of the equipment above. The warm air can cause an over
temperature condition in the equipment above.
y Ensure that cables from other equipment do not obstruct the airflow through the chassis or
impair access to the power supplies or cards.
y Bolt the rack to the floor for stability.
y Load the rack from the bottom to the top, with the heaviest system at the bottom.
y If there is equipment already installed in the rack, select the location for the system carefully
considering the size of the system:
