Install the Data Domain cable management assembly

Steps

  1. Take out the cable management assembly (CMA) from its packaging.
  2. Locate the two blue knobs (on the left and right sides of the CMA) in the back which you will need to pull away from the side of the CMA brackets to install the CMA in the rack.

  3. Pull the knobs away from the side of the CMA brackets towards the direction of the white arrow (see picture) and turn the blue knobs in the direction of the yellow arrow (on the left and right sides of the CMA) so the tip of the knob is pulled away from the side of the bracket to fit in the rail slot.

  4. Locate the slots and the hole in the Data Domain rail to attach the CMA by following the arrows in the picture. Align and insert the CMA tabs in the slots and the blue knob in the hole of the rail bracket on both sides.

  5. Insert cable management assembly into rear of rack mount rails.
  6. When the cable management assembly is securely installed into the rack mount rails, then rotate the two blue knobs clockwise or counterclockwise to lock the cable management assembly into the rack mount rails.
  7. To adjust the CMA position up or down, pull on the orange latches and pull up or down on the arm simultaneously as needed for accessing the power cables.
    NOTE You do not need to remove the CMA to access the I/O modules, the managements module, and the powers supply units for removal and replacement. Just adjust the CMA arms.
  8. For HA systems, repeat this procedure to install the CMA for the second node.
