12 HP BladeSystem p-Class Enclosure Installation Guide
Compaq branded 9000 Series racks provide proper server cooling from flow-
through perforations in the front and rear doors that provide 65 percent open area
for ventilation.
CAUTION: Always use blanks to fill empty spaces in
enclosures. This arrangement ensures proper airflow. Using an
enclosure without the proper blanks results in improper cooling that can
lead to thermal damage.
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the
rack in a well ventilated, climate-controlled environment.
The operating temperature inside the rack is always higher than the room
temperature and is dependent on the configuration of equipment in the rack.
Check the TMRA for each piece of equipment before installation.
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
equipment or to increase the internal rack temperature beyond the
maximum allowable limits.
Do not exceed the manufacturer’s TMRA.
Power requirements
WARNING: A risk of fire or damage to the equipment
exists.
Each AC power cord for the power enclosure has an electrical
rating based on the model and power supply configuration. The
rating is marked on the side of the enclosure.
