Install 48U Heavy Duty Rack Extension

See this topic to learn how to install 48U Heavy Duty Rack Extension.

  • Each unit of extension module comes with additional capacity of one unit 0U PDU to each side of the rack.

  • Each rack cabinet supports up to two units of rack extension (one to the front and one to the rear side). However, if the rear side has been installed with the Rear Door Heat Exchanger, the rack extension cannot be installed.

  • If there is a plan to install baying kit while only one of the adjacent cabinets will be installed with extension, make sure to install the baying kit first (see Install the baying kit). Then, as preparation for this procedure, remove the two screws from the upper and lower part of the cabinet that will be installed with the extension kit, and jump to Step 4.

  1. Secure an extension side panel to the side of the rack with seven screws, and repeat the step on the other extension panel.
