  • Page 17: Airflow

    Mechanical Considerations Airflow The server fans draw air into the equipment enclosure. After heated the air, the server fans force the air across the Liebert XDR’s two coils. The Liebert XDR has a low air-side pressure drop (similar to a rack with perforated doors).
  • Page 18: Installation

    Installation NSTALLATION Installing the Rack-Mounting Kit onto the Rack The Liebert XDR module mounts on the rear of the rack using a mounting kit. The mounting kit secures the Liebert XDR's frame to the rack. Two rails are attached to the rear of the rack with M6 x 12 bolts.
  • Page 19: Door Safety Catch

    Installation Door Safety Catch The door safety catch prevents the door from opening beyond 110°. When the door is fully open, the safety catch will hold door in place. To release the door, push up on the door catch and close the door.
