Procedure

1. Mark the mounting holes for the expandable guide rails and mounting brackets on the guide rails.

   Positions of mounting brackets only need to be marked on the front mounting rails, whereas positions of expandable guide rails must be marked on both the front and rear mounting rails. Keep the mounting holes on the front and rear mounting rails on the same horizontal plane.

   1. Use a pair of scissors to cut the installation template along the CloudEngine 16804 cutting line.
      Figure 5-2 Cutting the installation template
      

   2. Determine the device installation position in the cabinet or rack. Two persons hold the installation template, align the mounting holes on the installation template with those on the mounting rails of the cabinet or rack, and fix the installation template on the mounting rails. Mark the mounting holes for the mounting brackets and expandable guide rails, and then remove the installation template.

2. Install floating nuts in the marked mounting holes.
   • You can use a floating nut mounting bar to facilitate installation of floating nuts.
   • When installing the CloudEngine 16804, eight floating nuts are used to secure the mounting brackets, and 10 floating nuts are used to secure the guide rails (two for the front end and three for the rear end of each guide rail).

3. Install expandable guide rails.
   • When installing expandable guide rails, ensure that the front and rear ends of each guide rail are on the same horizontal plane.
   • For a third-party cabinet or rack, if you do not use the expandable guide rails delivered with the device, use a tray (with a minimum load bearing capacity of 324 kg) instead.
   1. Adjust the length of the guide rails and place them in marked positions on the mounting rails by the plate at the front end and hook at the rear end. The bottom edges of the guide rails must be aligned with scale lines on the mounting rails. Then secure the guide rails with M6 screws. See callout 1 in Figure 5-5. Tighten the M6 screws with a torque of 1.96 N m.
   2. Use M6 screws to secure the air baffle to the guide rails. See callout 2 in Figure 5-5. Tighten the M6 screws with a torque of 1.96 N m.

4. Install the device in the cabinet or rack.
   1. Move the device into the cabinet. See callout 1 in Figure 5-6.

      When moving the device into the cabinet, move the device by the load bearing handles at both sides of the device. Do not lift or drag the chassis by the handles of any modules in the chassis; otherwise, the device and modules will be damaged. Place the rear bottom of the device on the guide rails, and then horizontally push the chassis in a gentle and smooth manner until the mounting brackets on the chassis are completely attached to the front mounting rails. When pushing the chassis, prevent the chassis from colliding with the captive screws on the mounting brackets.

   2. Tighten the captive screws on mounting brackets. See callout 2 in Figure 5-6. Tighten the captive screws with a torque of 1.76 N·m.
