    1. Installing Cage Nuts, If Needed
    2. Installing the Open-Frame Rack Mounting Shelf
    3. Installing the Center-Mounting Brackets

    Installing Cage Nuts, If Needed

    Insert cage nuts, if needed, into the holes listed in Table 1 and Table 2. The hole distances are relative to the standard U division on the rack that is aligned with the bottom of the mounting shelf.

    To install cage nuts in an open-frame rack:

    1. On the rear side of both rack rails, insert cage nuts in the holes specified for the open-frame mounting shelf (see Table 1).
    2. On the front side of both rack rails, insert cage nuts in the holes specified for mounting the chassis (see Table 2).

    Installing the Open-Frame Rack Mounting Shelf

    Before mounting the chassis in an open-frame rack, you must first install the open-frame rack mounting shelf.

    To install the open-frame rack mounting shelf (see Figure 1):

    1. On the rear of each rack rail, partially insert a mounting screw into the highest hole specified in for the open-frame rack mounting shelf.
    2. Install the open-frame mounting shelf on the rack. Hang the shelf over the mounting screws using the keyhole slots located near the top of the shelf flanges.
    3. Partially insert screws into the open holes in the flanges of the open-frame rack mounting shelf.
    4. Tighten all the screws completely.

    Installing the Center-Mounting Brackets

    The center-mounting brackets are used to install the router into an open-frame rack.

    To install the center-mounting brackets to the chassis:

    1. Align the center-mounting brackets with the holes located on either side of the chassis. (see Figure 2).
    2. Partially insert the screws as shown in Figure 2.
    3. Tighten all screws.
