Installing the Router into a Cabinet

Installing the Router into a Cabinet


  • 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
  • M4 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. Install two floating nuts on each front mounting rail. Leave a mounting hole between the two floating nuts on the same mounting rail.

    • The length of three adjacent mounting holes may not be 1 U. Observe the scale ticks on the mounting rails when installing floating nuts.
    • You can use a flat-head screwdriver to install floating nuts.

  3. Move the router into the cabinet. Support the bottom of the router with one hand and tighten the M6 screws on the mounting brackets with the other hand. Tighten the lower screws first, and then the upper screws.
