If you are installing a TX Matrix router, or a T640 router that you intend to integrate into
a routing matrix, consider these guidelines to facilitate the integration:
If you will be installing a fully configured centralized configuration, as described in
"Centralized Configuration" on page 58 (one TX Matrix router and four T640 routers),
plan to use a minimum of three racks side by side.
If you will be installing a fully configured distributed configuration, as described in
"Distributed Configuration" on page 59 (one TX Matrix router and four T640 routers),
plan to use one rack for the TX Matrix router, and two through four racks for the T640
routers (depending on whether you plan to install one or two T640 routers in a single
rack).
Account for the total weight of the routing matrix. One TX Matrix router and four
maximally configured T640 routers weigh approximately 2755 lb (1250 kg).
If you are installing the T640 router in the bottom of an empty rack, reserve the top of
the rack for the future installation of another T640 router.
We recommend that you install the TX Matrix router in its own dedicated rack. If you
must install another device in the rack, consider the height and weight of the TX Matrix
router and the fiber-optic array cable management above the chassis, including the
optional cable shelf assembly.
The TX Matrix router is designed for installation in a rack that complies with either of the
following standards:
A 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document
number EIA-310-D) published by the Electronics Industry Association
( ).

A 600-mm rack as defined in the four-part Equipment Engineering (EE); European
telecommunications standard for equipment practice (document numbers ETS 300
119-1 through 119-4) published by the European Telecommunications Standards Institute
( http://www.etsi.org ). The horizontal spacing between the rails in a rack that complies
with this standard is usually wider than the TX Matrix router's mounting brackets, which
measure 19 in. (48.3 cm) from outer edge to outer edge. Use approved wing devices
to narrow the opening between the rails as required.
