Unpacking and Mounting the ACX4000 Router

Unpacking an ACX4000 Router

The ACX4000 routers are shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box.


ACX4000 routers are maximally protected inside the shipping carton. Do not unpack the routers until you are ready to begin installation.

To unpack the router and prepare for installation, you need the following tools:

  • Blank panels to cover any slots not occupied by a component

To unpack the router:

  1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough room to remove the system components.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Remove the accessory box and verify the contents in it against the parts inventory on the label attached to the carton.
  5. Pull out the packing material holding the router in place.
  6. Verify the chassis components received against the packing list included with the router. An inventory of parts provided with the router is provided in Parts Inventory (Packing List) for an ACX4000 Router.
  7. Save the shipping carton and packing materials in case you need to move or ship the router later.

You must provide additional mounting screws if needed that are appropriate for your rack or cabinet to mount the chassis on a rack or a cabinet.

Installing the ACX4000 Mounting Brackets

To attach the mounting brackets, you need the following tools:

  • Phillips (+) screwdriver, number 2

Two mounting brackets for front mounting ship with the router (see Figure 1).

To attach both mounting brackets to either the front or rear of the chassis:

  1. Align the bracket with the two sets of mounting holes.
  2. Insert the four screws at the top and bottom of the bracket and tighten each partially.
  3. Tighten the four screws completely.
  4. Repeat the procedure for the other bracket.

Installing the ACX4000 Router in the Rack


The router can be installed horizontally in a rack or cabinet. For additional installation options, contact JTAC.

To install the router in the rack (see Figure 2):


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.


One person must be available to lift the switch while another secures it to the rack.


If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

  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. Position the router in front of the rack or cabinet.
  3. Hold onto the bottom of the chassis and carefully lift it so that the mounting brackets contact the rack rails.

    To prevent injury, keep your back straight and lift with your legs, not your back. Avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

  4. Align the mounting brackets with the holes in the rack rails.
  5. Install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.
  6. 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.
