After connecting and powering on the Hub, check all LEDs to ensure that the sys-
tem is operating properly.
Make sure the Main Hub is grounded. The warranty does not cover damage
caused when an ungrounded Hub is powered on.
NOTE: Use a 50 ohm terminator on any unused power combiner/splitter ports.
Figure 7-21 shows how to connect two Hubs to a duplex repeater or base station. You
need to use one circulator and one more coaxial jumper cable, as shown.
