Using Mounting Brackets and L-Shaped Guide Rails (AR2220)

Using Mounting Brackets and L-Shaped Guide Rails (AR2220)


  • Leave at least 50 mm of clearance around the router for heat dissipation.
  • Seen from the front panel of the router, the airflow of the router is left to right.
  • If multiple routers are installed in a cabinet, it is recommended that at least 1 U of space (1 U = 44.45 mm) be kept between two routers. These routers must have the same airflow direction; otherwise, heat dissipation is affected by hot air circulation.

Make sure the following before the installation:

  • The cabinet is well fixed.
  • The router installation position in the cabinet is determined and arranged properly.
  • The router to be installed is available and located near the cabinet for convenient movement.

Tools and Accessories

  • Phillips screwdriver
  • Flat-head screwdriver
  • Floating nuts
  • Mounting brackets
  • L-shaped guide rails (separately purchased)
  • M4 screws
  • M5 screws
  • M6 screws


  1. Use a Phillips screwdriver to fix the mounting brackets to both sides of the router with M4 screws.


    The mounting brackets can be installed on both sides close to the front panel or rear panel.

  2. Mark the positions of L-shaped guide rails and floating nuts.

  3. Install the floating nuts and L-shaped guide rails.
    1. Ensure that the floating nuts on the left and right are on the same horizontal plane. Use a flat-head screwdriver to install four floating nuts in the marked positions on the front mounting rails, two on left and two on right.
    2. The bottom edges of the L-shaped guide rails must be in line with the bottom edges of the marked mounting holes. Use a Phillips screwdriver to fix the L-shaped guide rails in the marked positions with M5 screws.

  4. Install the router into the cabinet.
    1. Move the router into the cabinet, place the router on the L-shaped guide rails, and gently push the router into the cabinet until the mounting brackets are completely attached to the front mounting rails.
    2. Use M6 screws to fix the mounting brackets on the cabinet.
