To install the large mounting shelf on the front rack rail (see Figure 39 on page 76):
On the front of each front rack rail, partially insert a mounting screw into the hole
1.
containing the lowest cage nut.
Install the large mounting shelf on the front rack rails. Rest the bottom slot of each
2.
flange on a mounting screw.
Tighten all the screws completely.
3.
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
1.
flange.
Place one of the spacer bars over a flange of the installed large mounting shelf. Position
2.
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 40 on
page 78).
