Check Main Hub LEDs.
After connecting and powering on the Main Hub, check all LEDs to ensure that
the system is operating properly.

Use a 50 ohm terminator on any unused power combiner/splitter ports.
Figure 7-10 shows connecting two Main Hubs to a simplex repeater or base station.
Connecting two Main Hubs increases the total number of supportable RAUs from 32
to 64. Two Main Hubs support up to 8 Expansion Hubs which in turn support up to 64
RAUs.
