Third-party thermal considerations

CAUTION
If a third-party rack is used, observe the following additional requirements
to ensure adequate airflow and to prevent damage to the equipment:
Front and rear doors: If the 42U server rack includes closing front
•
and rear doors, allow 830 square inches (5,350 sq cm) of hole
evenly distributed from top to bottom to permit adequate airflow
(equivalent to the required 64 percent open area for ventilation). Be
sure that the option equipment does not impede airflow to the rack-
mountable servers or increase the internal rack temperature beyond
the specified maximum rating.
Side: The clearance between the installed rack component and the
•
side panels of the rack must be a minimum of 2.75 inches (7 cm).
CAUTION
Always use blanking or filler panels to fill all remaining empty front panel
U-spaces in the rack. This arrangement ensures proper airflow. Using a
rack without installing blanking panels to fill empty U-spaces results in
improper cooling that can lead to thermal damage.
CAUTION
Be sure that the option equipment installed does not exceed the
Manufacturer's Maximum Recommended Ambient Operating Temperature.
NOTE
For additional information, refer to the Setup and Installation Guide or the
Documentation CD provided with the server, or to the server documentation
