Qualified Ethernet Switches
Q-Sys uses layer 3 (DSCP) QoS. This type of QoS is deployed differently on different networks and therefore requires user intervention to set up
properly. Because of this complexity, switches which are not managed are not acceptable for Q-Sys. For more details about network and switch setup,
refer to the Help File in Q-Sys Designer. For more details about the following switches, refer to the manufacturers’ website. The following switches
have been tested and qualify for use with a Q-Sys™ network.
NOTE!:
Refer to the Q-Sys Online help on the QSC website for the latest list of switches.
