Installing the MX960 Mounting Hardware for Front-Mounting in an Open-Frame Rack

 

Before front-mounting the router in an open-frame rack, install the large mounting shelf on the rack, and remove the mounting brackets from the chassis. The small mounting shelf is not needed.

Table 1 specifies the holes in which you insert screws to install the mounting hardware in an open-frame rack (an X indicates a mounting hole location). The hole distances are relative to one of the standard U divisions on the rack. For reference, the bottom of all mounting shelves is at 0.04 in. (0.02 U) above a U division.

To install the large mounting shelf (see Figure 1):

  1. On the rear of each rack rail, install cage nuts, if needed, in the holes specified in Table 1 for the large shelf.
  2. Partially insert a mounting screw into the highest hole specified in Table 1.
  3. Hange the shelf over the mounting screws using the keyhole slots located near the top of the large shelf flanges.
  4. Partially insert screws into the open holes in the flanges of the large shelf.
  5. Tighten all the screws completely.
