Installing the TX Matrix Mounting Hardware for an Open-Frame Rack

 

Install the large mounting shelf on the rack. If you are front-mounting the TX Matrix router, you must also remove the mounting brackets from the chassis. The small mounting shelf and the spacer bars are not needed.

Installing the Cage Nuts

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.

Installing the Large Mounting Shelf

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

  1. On the rear of each rack rail, partially insert a mounting screw into the lowest hole specified in Table 1 for the large shelf.
  2. Install the large shelf on the rack. Rest the bottom slot of each flange on a mounting screw.
  3. Partially insert screws into the open holes in the flanges of the large shelf.
  4. Tighten all the screws completely.

Removing the Spacer Bars

The TX Matrix router is shipped with each spacer bar attached to the rear of a front-mounting flange. Remove each spacer bar by removing the screws that fasten it to the front-mounting flange.
