Installing the TX Matrix Plus Mounting Hardware for an Open-Frame Rack
Assembling the Open-Frame Rack Mounting Shelf
The open-frame rack mounting shelf is shipped in three pieces: one bottom piece and two side pieces. Eight screws are provided. To assemble the open-frame rack mounting shelf:
- Place one side of the mounting shelf over the holes on the bottom shelf piece.
- Partially insert screws into the open holes in the flanges of the open-frame rack mounting shelf.
- Tighten all the screws completely.
- Place the other side of the mounting shelf over the holes on the bottom shelf piece.
- Partially insert screws into the open holes in the flanges of the open-frame rack mounting shelf.
- Tighten all the screws completely.
Installing Cage Nuts, If Needed
Insert cage nuts, if needed, into the holes listed in Table 1 and Table 2 (an X indicates a mounting hole location). The hole distances are relative to the standard U division on the rack that is aligned with the bottom of the mounting shelf and rear support bracket.
To install cage nuts in an open-frame rack:
- On the rear side of both rack rails, insert cage nuts in the holes specified for the open-frame mounting shelf (see Table 1).
- On the front side of both rack rails, insert cage nuts in the holes specified for mouting 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):
- On the rear of each rack rail, partially insert a mounting screw into the highest hole specified in Table 1 for the open-frame rack mounting shelf.
- Install the open-frame rack mounting shelf on the rack. Hang the shelf over the mounting screws using the keyhole slots located near the top of the shelf flanges.
- Partially insert screws into the open holes in the flanges of the open-frame rack mounting shelf.
- Tighten all the screws completely.
Insert screws in the holes specified in Table 3 (an X indicates a mounting hole location). The hole distances are relative to the standard U division on the rack that is aligned with the bottom of the mounting shelf.
