Determine the number of cables needed based on your planned configuration.
Review the maximum distance allowed for each cable. Choose the length of cable
based on the distance between the hardware components being connected.

Considerations" on page 65.
Plan the cable routing and management.

Distributed Configuration on page 59
A fully loaded routing matrix configuration consists of one TX Matrix router, four T640
routers, three to five 44-U, seismic-rated racks, 20 fiber-optic array cables, 10 Ethernet
cables, and a cable management system. There are two types of configurations to
consider when you plan and prepare for the installation of the routing matrix—centralized
and distributed.
In the centralized configuration, three racks are placed next to each other in a row. Figure
29 on page 59 and Figure 30 on page 59 show a rack view and a top view of a centralized
configuration in which the left and center racks each hold two T640 routers, and the
right rack holds the TX Matrix router. In Figure 30 on page 59, each connection to a T640
router represents five fiber-optic array cables.
NOTE: In the configuration shown in Figure 29 on page 59, if the raceway is
less than 1 m above the racks, 5-m fiber-optic array cables are usually long
enough to connect the system.
In the centralized configuration, the total weight of the routing matrix and the heat it
generates are concentrated in a relatively small area. You must ensure that your site can
support the weight and your site cooling can adequately dissipate the heat. For physical
and environmental specifications, see Table 31 on page 333 and Table 32 on page 335.
