Using Mounting Brackets and Mounting Bracket Guide Rails (AR2204/AR2220E/AR2204E series)

Using Mounting Brackets and Mounting Bracket Guide Rails (AR2204/AR2220E/AR2204E series)

Context

  • 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.
NOTE:

The procedures and methods for installing AR2204, AR2220E, and AR2204E series routers into a cabinet are the same. The following procedure installs an AR2204 router into cabinet.

Tools and Accessories

  • Phillips screwdriver
  • Flat-head screwdriver
  • Floating nuts
  • Mounting brackets
  • Mounting bracket guide rails
  • M4 screws
  • M6 screws

Procedure

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

    NOTE:

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

  2. Install two floating nuts on each of the front and rear mounting rails. Leave a mounting hole between the two floating nuts on the same mounting rail.

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


  3. Fix the mounting bracket guide rails on the rear mounting rails.



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