Two Galaxy network processors 816 control the overall system, and two RMServers on the network are responsible for health monitoring and troubleshooting.

The Galaxy 816 are connected to the master switch, located in the stadium control room, via AVB/TSN, with bidirectional signals routed over a fiber-optic network from the room to the eleven local switches, distributed around the stadium.

Each local switch connects to its assigned group of CAL speakers via Cat-5e cable. All switches are Extreme Networks X440-G2 series.
