Installing the Router into a Cabinet

Installing the Router into a Cabinet

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 AR2240 and AR2240C routers into a cabinet are the same. The following procedure installs an AR2240 router into cabinet.
  • The procedures and methods for installing AR3260 and AR3670 routers into a cabinet are the same. The following procedure installs an AR3260 router into cabinet.

Tools and Accessories

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

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.

    • Figure 6-1 shows installation of mounting brackets on an AR2240.
    • Figure 6-2 shows installation of mounting brackets on an AR3260.

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

    • An AR2240 router is 2 U high, which is the distance between six mounting holes. Mark the mounting holes for L-shaped guide rails and floating nuts with a marker.
    • An AR3260 router is 3 U high, which is the distance between nine mounting holes. Mark the mounting holes for L-shaped guide rails and floating nuts with a marker.


  3. Install the floating nuts and L-shaped guide rails.

    NOTE:

    The methods for installing floating nuts and L-shaped guide rails for the AR2240 and AR3260 routers are the same, except that the installation positions of the floating nuts and L-shaped guide rails differ. An AR2240 router is used as an example here to describe the installation procedure.

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



  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.
