Installing the MX480 Router Mounting Hardware for a Rack or Cabinet

The router can be installed in a four-post rack or cabinet or an open-frame rack. Install the mounting hardware on the rack before installing the router.

Install the mounting shelf, which is included in the shipping container, before installing the router. We recommend that you install the mounting shelf because the weight of a fully loaded chassis can be up to 163.5 lb (74.2 kg).

Table 1 specifies the holes in which you insert cage nuts and screws to install the mounting hardware required (an X indicates a mounting hole location). The hole distances are relative to one of the standard U divisions on the rack. The bottom of all mounting shelves is at 0.02 in. above a U division.

Moving the Mounting Brackets for Center-Mounting the MX480 Router

Two removable mounting brackets are attached to the mounting holes closest to the front of the chassis. You can move the pair of brackets to another position on the side of the chassis for center-mounting the router.

To move the mounting brackets from the front of the chassis toward the center of the chassis:

  1. Remove the three screws at the top and center of the bracket.
  2. Pull the top of the bracket slightly away from the chassis. The bottom of the bracket contains a tab that inserts into a slot in the chassis.
  3. Pull the bracket away from the chassis so that the tab is removed from the chassis slot.
  4. Insert the bracket tab into the slot in the bottom center of the chassis.
  5. Align the bracket with the two mounting holes located toward the top center of the chassis.

    There is no mounting hole in the center of the chassis that corresponds to the hole in the center of the bracket.

  6. Insert the two screws at the top of the bracket and tighten each partially.

    Two screws are needed for mounting the bracket on the center of the chassis. You do not need the third screw.

  7. Tighten the two screws completely.
  8. Repeat the procedure for the other bracket.

Installing the MX480 Router Using a Mechanical Lift

Because of the router's size and weight—up to 163.5 lb (74.2 kg) depending on the configuration—we strongly recommend that you install the router using a mechanical lift. To make the router light enough to install with a lift, you must first remove most components from the chassis.

Caution

Before front mounting the router in a rack, have a qualified technician verify that the rack is strong enough to support the router's weight and is adequately supported at the installation site.

To install the router using a lift (see Figure 8):

  1. Ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance.
  2. Load the router onto the lift, making sure it rests securely on the lift platform.
  3. Using the lift, position the router in front of the rack or cabinet, centering it in front of the mounting shelf.
  4. Lift the chassis approximately 0.75 in. above the surface of the mounting shelf and position it as close as possible to the shelf.
  5. Carefully slide the router onto the mounting shelf so that the bottom of the chassis and the mounting shelf overlap by approximately two inches.
  6. Slide the router onto the mounting shelf until the mounting brackets contact the rack rails. The shelf ensures that the holes in the mounting brackets of the chassis align with the holes in the rack rails.
  7. Move the lift away from the rack.
  8. Install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.
  9. Visually inspect the alignment of the router. If the router is installed properly in the rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side and the router should be level.
