    Installing the M40e Mounting Hardware for an Open-Frame Rack

    To prepare to mount the router into an open-frame rack, install the mounting shelf on the rack. Install cage nuts, if needed.

    For open-frame racks, center-mounting the chassis is preferable to front-mounting because the more even distribution of weight provides greater stability. You use the center-mounting brackets to center-mount the chassis in an open-frame rack; you use the front-mounting flanges to front-mount the chassis in an open-frame rack.

    Installing Cage Nuts, If Needed

    Install cage nuts, if needed:

    1. On each front rack rail, install a cage nut 0.88 in. (2.2 cm) up from the bottom of a U division.
    2. Insert a cage nut behind each hole where you plan to install the flanges of the mounting shelf.

    Installing the Mounting Shelf in an Open-Frame Rack

    To install the mounting shelf in an open-frame rack:

    1. On the front of each front rack rail, partially insert a mounting screw 0.88 in. (2.2 cm) up from the bottom of a U division.
    2. Install the shelf on the front rack rails. Rest the bottom slot of each flange on one of the mounting screws.
    3. Partially insert a mounting screw into the top hole in each flange of the shelf.
    4. Tighten all the screws completely.

    Removing the Center-Mounting Brackets

    If you plan to front-mount the router, remove the center-mounting brackets.

    To remove the center-mounting brackets:

    1. Loosen the screws at the top and bottom of each bracket.
    2. Remove the brackets from both sides of the chassis.
