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:
- On the front rack rails, install cage nuts in the holes
specified in Table 1 for
the large mounting shelf and the spacer bars.
- 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.
Table 1: Four-Post or Cabinet Rack Mounting Hole Locations
Hole | Distance Above U Division | Large Shelf | Spacer Bars | Small Shelf |
|---|
60 | 34.75 in. (88.3 cm) | 19.86 U | | X | |
51 | 29.51 in. (74.9 cm) | 16.86 U | | X | |
42 | 24.26 in. (61.6 cm) | 13.86 U | | X | |
33 | 19.01 in. (48.3 cm) | 10.86 U | | X | |
24 | 13.76 in. (34.9 cm) | 7.86 U | | X | |
15 | 8.51 in. (21.6 cm) | 4.86 U | | X | X |
12 | 6.76 in. (17.1 cm) | 3.86 U | | | X |
9 | 5.01 in. (12.7 cm) | 2.86 U | | | X |
6 | 3.26 in. (8.3 cm) | 1.86 U | | X | X |
3 | 1.51 in. (3.8 cm) | 0.86 U | | | X |
2 | 0.88 in. (2.2 cm) | 0.50 U | X | | |
Installing the Large Mounting Shelf
To install the large mounting shelf on the front rack
rail (see Figure 1):
- On the front of each front rack rail, partially insert
a mounting screw into the hole containing the lowest cage nut.
- Install the large mounting shelf on the front rack rails.
Rest the bottom slot of each flange on a mounting screw.
- 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.
- Remove each spacer bar by removing the screws that fasten
it to the front-mounting flange.
- 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).
- 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.
- Repeat Steps 2 and 3 for the other spacer bar.
- Tighten all the screws completely.

Bar on the Rack
Installing the Small Shelf
- On the back of each rear rack rail, partially insert a
mounting screw into the hole containing the lowest cage nut.
- 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.
- Partially insert screws into the open holes in the flanges
of the small mounting shelf.
- Tighten all the screws completely.
