Abstract: An aisle enclosure system including ceiling bracket assemblies, ceiling panels, vertical blanking panels, aisle duct adaptors, and accessory rails, for use with equipment racks and ceiling structures in hot-aisle and cold-aisle data centers. The ceiling assemblies may be mounted to the tops of the racks or may be suspended from an area above the racks. The aisle enclosure system further includes a moveable structure that is configured and adapted to position a ceiling panel in an closed position when the moveable structure is in a first position, and position the ceiling panel in an open position when the moveable structure is in a second position, where the moveable structure is configured and adapted to move from the first position to a second position in response to an alarm condition.

Abstract: Adjustable blanking panels for use with equipment racks and enclosures to cover or fill in vacant sections of the rack or enclosure, to prevent the circular flow and reentry of high temperature air into the intake of electrical and computer equipment. The adjustable blanking panels include a generally rectangular base frame that defines opposing left and right side channels, and a generally rectangular shield that is adapted to be inserted into the side channels and slide relative to the base frame, to adjust the height of the panel to the size of the vacant section. The adjustable blanking panel may further include a lip that may be used to raise or lower the shield.
