Installing a Sun Disk Shelf

Use the following procedure to install a Sun Disk Shelf.

Starting at the bottom of the cabinet, locate the appropriate rack unit (RU) height. Install Disk Shelves below controllers to prevent rack from tipping. The Sun Disk Shelf requires four standard mounting units (4RU) of vertical space in the cabinet.


Caution  -  This procedure requires a minimum of two people, or a mechanical lift, because of the weight of the chassis. Attempting this procedure alone could result in equipment damage or personal injury. Always load the heaviest equipment (disk shelves) at the bottom of the rack.

Before You Begin

Extend all anti-tilt and stabilization devices from the bottom of the rack.

  1. If you are using a universal 19-inch or Sun Rack II cabinet, snap an M6 square cage nut into the 4U location where you will be installing the system. Install in the top and bottom holes.

  2. Install appropriate rail plates in four locations on the rack (2 front and 2 back) by aligning the two pins on the rail plate with holes on the cabinet rails.
  3. Insert M6 screws in the top and bottom holes of each rail plate and tighten (8 total places).

  4. Install each rail by first aligning the front pins of the rack adapter plates with corresponding holes in the front of the rail, then adjust the rail to fit the rack and insert the pins from the rear rack adapter plates into the corresponding holes of the rail.
  5. Install four 8-32 screws into the four remaining front and rear holes of each rack rail (16 total).

  6. Using a mechanical lift or two people, one at each side of the shelf or controller, carefully lift and rest the shelf on the bottom ledge of the left and right rails. The following graphic illustrates the chassis insertion.

  7. Carefully slide the shelf into the cabinet until the front flanges of the shelf touch the vertical face of the rack.
  8. Tighten the captive screws on each side of the front of the shelf to secure the shelf to the rack.
  9. At the back of the disk shelf, slide a system locking clip onto each lower corner of the chassis.
