CAUTION: Always use blanking panels to fill empty vertical
spaces in the rack. This arrangement ensures proper airflow. Using a
rack without blanking panels results in improper cooling that can lead to
thermal damage.
The Compaq 9000 and 10000 Series racks provide proper server cooling from
flow-through perforations in the front and rear doors that provide 64 percent
open area for ventilation.
CAUTION: When using a Compaq branded 7000 Series rack, you
must install the high airflow rack door insert [P/N 327281-B21 (42U) or
P/N 157847-B21 (22U)] to provide proper front-to-back airflow and
cooling.
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 rack includes closing front and rear
doors, you must allow 5,350 sq cm (830 sq in) of holes evenly
distributed from top to bottom to permit adequate airflow (equivalent
to the required 64 percent open area for ventilation).
• Side—The clearance between the installed rack component and the
side panels of the rack must be a minimum of 7 cm (2.75 in).
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the
system in a well-ventilated, climate-controlled environment.
The maximum recommended ambient operating temperature (TMRA) for most
server products is 35°C (95°F). The temperature in the room where the rack is
located must not exceed 35°C (95°F).
CAUTION: To reduce the risk of damage to the equipment when
installing third-party options:
• Do not permit optional equipment to impede airflow around the
server or to increase the internal rack temperature beyond the
maximum allowable limits.
• Do not exceed the manufacturer’s TMRA.
