Installing the TX Matrix Mounting Hardware for a Four-Post Rack or Cabinet

 

Before installing the TX Matrix router into a four-post rack or cabinet, install the large and small mounting shelves and the spacer bars on the rack.

Installing the Cage Nuts

To install the cage nuts for a four-post rack or cabinet:

  1. On the front rack rails, install cage nuts in the holes specified in Table 1 for the large mounting shelf and the spacer bars.
  2. On the rear rack rails, install cage nuts in the holes specified in Table 1 for the small mounting shelf.

Table 1 specifies the holes in which you insert cage nuts and screws to install the mounting hardware required in a four-post or cabinet rack (an X indicates a mounting hole location). The hole distances are relative to one of the standard U divisions on the rack. 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 on the front rack rail (see Figure 1):

  1. On the front of each front rack rail, partially insert a mounting screw into the hole containing the lowest cage nut.
  2. Install the large mounting shelf on the front rack rails. Rest the bottom slot of each flange on a mounting screw.
  3. Tighten all the screws completely.

Installing the TX Matrix Spacer Bars on the Four-Post Rack

The TX Matrix router is shipped with each spacer bar attached to the rear of a front-mounting flange. If you are mounting the TX Matrix router in a four-post rack or cabinet, you must install the spacer bars on the rack before you mount the chassis.

  1. Remove each spacer bar by removing the screws that fasten it to the front-mounting flange.
  2. Place one of the spacer bars over a flange of the installed large mounting shelf. Position the notch in the rear of the spacer bar so the upper part of the bar is flush with the rack rail and the lower part is flush with the flange of the shelf (see Figure 2).
  3. Insert a mounting screw into each of the nonthreaded holes in the recesses of the spacer bar to secure the spacer bar. Each hole should have a cage nut behind it.
  4. Repeat Steps 2 and 3 for the other spacer bar.
  5. Tighten all the screws completely.

Installing the Small Shelf

  1. On the back of each rear rack rail, partially insert a mounting screw into the hole containing the lowest cage nut.
  2. Install the small mounting shelf on the back rack rails. Rest the bottom slot of each flange on a mounting screw. The small mounting shelf installs on the back of the rear rails, extending toward the center of the rack. The bottom of the small mounting shelf should align with the bottom of the large mounting shelf.
  3. Partially insert screws into the open holes in the flanges of the small mounting shelf.
  4. Tighten all the screws completely.
