Connections to More than Six Hosts Using Ethernet Switches
To expand the number of hosts connected to the IP network, you can use two Ethernet
switches supporting STP (spanning tree protocol). If a host unit experiences an outage,
the system continues service.

Turning On Redundant Controllers
When turning on redundant controllers the first time, start the Secondary controller first,
followed by the Primary controller.
To turn on redundant controllers:
1. Make sure both system controllers are disconnected from the customer and Matrix
IP networks. All Ethernet cables should be unplugged from the units.
2. Make sure controllers are labeled as Primary and Secondary.
3. Turn on the Secondary controller first by plugging the AC cable into an AC power
source. There is no power switch. The unit is on when the LED on the front panel is
green.
4. Turn on the Primary controller.
5. Connect Ethernet cables to both system controllers, following the network plan
provided by your DAS integrator.
