HP ml310 Manual Do Utilizador

 

HP servers draw in cool air through the front and expel warm air through the 
rear. Therefore, the front and rear rack doors must be adequately ventilated to 
allow ambient room air to enter, and allow the warm air to escape from the 
cabinet. 

  CAUTION:  To prevent improper cooling and damage to the 

equipment, do not block the ventilation openings. 

The 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). 

When vertical space in the rack is not filled by a server or rack component, the 
gaps between the components cause changes in airflow through the rack and 
across the servers. Cover all gaps with blanking panels to maintain proper 
airflow. 

  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. 

 

To ensure continued safe and reliable equipment operation, install or position the 
system in a well-ventilated, climate-controlled environment.
