      specifications refer to a sytem that is fully extended from the rack for 
      service. When in normal operation, there are no side clearance requirements 
      for the server as the air flow is from the front to rear. However, make 
      sure that any front or back cabinet doors are 63% open to allow adequate 
      airflow. This can be accomplished by removing the doors, or ensuring that 
      the doors have a perforated pattern that provides a 63% open area. |
