Installing with L-Shaped Guide Rails

L-shaped guide rails are designed for Huawei cabinets.

The servers are stackable when L-shaped guide rails are used.

1. Install the floating nuts.
   1. Determine the installation positions according to the cabinet device installation plan.

      Floating nuts are used to tighten screws.

      The spacing boundary is used as the reference for calculating device installation space. See Figure 5-4.

   2. Fasten the lower end of a floating nut to the target square hole in a mounting bar at the front of the cabinet.
   3. Use a floating nut hook to pull the upper end of the floating nut, and fasten it to the upper edge of the square hole. See Figure 5-5.

   4. Install a floating nut to the other front mounting bar in the same way.

2. Install the L-shaped guide rails.
   1. Position a guide rail horizontally in contact with the mounting bars in the cabinet.
   2. Tighten the screws to secure the guide rail. See Figure 5-6.

   3. Install the other guide rail in the same way.

3. Install the server.
   1. Lift the server. This task requires at least two people.
   2. Place the server on the guide rails and slide it into the cabinet. See (1) in Figure 5-7.

   3. When the two mounting ears of the server come into contact with the mounting bars on the cabinet, tighten their captive screws to secure the server. See (2) in Figure 5-7.

4. After the installation is complete, connect power cables, and connect network cables, VGA cables, and USB devices as required. Power on the server.
