“Qualified" switches will presumably work with Q-SYS, based on their published specifications and laboratory testing by QSC of at least one similar switch model. The list of qualified switches represents the extent of testing done by QSC and does not represent an exhaustive list of network equipment that meet Q-SYS requirements.
These lists are dynamic; as network vendors continue to develop new equipment, QSC continues to test additional switches and add them to their respective lists; check back for additions and updates. QSC tests the switches with one Q-SYS Core and one switch. In complex networks, even a qualified switch may cause connectivity issues if it is configured incorrectly. The Network section of the table of contents in the Q-SYS Help file provides details on switch setup, configuration, and network performance requirements. Our experience is that a Q-SYS system deployed on a network that meets all these requirements will function properly.
For further details about the following switches, see their manufacturers' web sites.
