If you are installing the TX Matrix chassis in an open-frame rack, ensure that the rack
1.
is in its permanent location and is secured to the building. Ensure that the installation
site allows adequate clearance for both airflow and maintenance. For details, see "TX
Matrix Clearance Requirements for Airflow and Hardware Maintenance" on page 63.
CAUTION: Before front-mounting the TX Matrix chassis in a rack, have a
qualified technician verify that the rack is strong enough to support the
TX Matrix router's weight and is adequately supported at the installation
site.
Position the TX Matrix chassis in front of the rack or cabinet, centering it in front of
2.
the mounting shelves. Use a pallet jack if one is available.
CAUTION: Do not lift the TX Matrix chassis using the installation handle
or the handles on the sides of the chassis. Use these handles only to help
position the TX Matrix chassis.
With two people in the front and two people in the back, hold the bottom of the chassis
3.
and carefully lift it onto the mounting shelves.
WARNING: To prevent injury, keep your back straight and lift with your
legs, not your back. Avoid twisting your body as you lift. Balance the load
evenly and be sure that your footing is solid.
With one person pulling on the installation handle from the rear of the rack or cabinet
4.
while two people push on the front-mounting flanges, slide the TX Matrix chassis onto
the mounting shelves until the mounting brackets or front-mounting flanges contact
the rack rails or spacer bars (depending on your type of installation). The shelves
ensure that the holes in the mounting brackets and the front-mounting flanges of the
chassis align with the holes in the rack rails.
If you are installing the TX Matrix chassis in a four-post rack or cabinet, install a
5.
mounting screw and a cage nut into each of the holes aligned with the threaded holes
in the spacer bars. If you are installing the TX Matrix chassis in an open-frame rack,
install a mounting screw into each of the open mounting holes aligned with the rack,
starting from the bottom.
Using a Phillips (+) screwdriver, number 2, loosen the captive screws on the installation
6.
handle completely, and remove the handle from the chassis.
Visually inspect the alignment of the TX Matrix router. If the TX Matrix chassis is
7.
installed properly in the rack, all the mounting screws on one side of the rack should
be aligned with the mounting screws on the opposite side and the TX Matrix chassis
should be level.
