Q-SYS NS Series Gen 2 - Network Switches
The Q-SYS NS Series Gen 2 switches offer a plug-n-play solution for Q-SYS
system installers intending to deploy a local, isolated AV network for media
distribution. The NS Series Gen 2 switches ship pre-loaded with a QSC
developed configuration tailored towards the real-time demands of Q-LAN
™
Audio and Video as well as Dante
and AES67 streams. The Q-SYS NS
Series Gen 2 switches eliminate the need for time consuming network
configuration and troubleshooting on site, thereby reducing labor costs,
minimizing system commissioning time and reducing the need for network
support specialists.
The Q-SYS NS Series Gen 2 switches include QSC developed AV&C (Audio, Video and Control) profiles that provide optimal
QoS (Quality of Service) configuration for Q-LAN
™
audio, Q-LAN
™
video, Dante
™
audio (standard and low latency modes), and
AES67 audio streaming formats. The preloaded configurations for the NS Series Gen 2 switches provide DSCP (Differentiated
Services Code Point) values appropriate for each AV&C profile in addition to advanced protocol detection and queue mapping to
ensure that all time-critical media data described above is prioritized appropriately for on-time delivery.
In order to ensure optimal performance for real-time media in situations with large amounts of multicast traffic, the Q-SYS NS Series
Gen 2 switches have preconfigured IGMP Querier and IGMP Snooping functions to facilitate multicast filtering and forwarding
whenever necessary.
The Q-SYS NS Series Gen 2 products are economical, enterprise grade, access class, managed network switch products.
The Q-SYS NS Series Gen 2 switches are NETGEAR AV Line M4250 series OEM hardware products that are preconfigured for
Q-SYS AV&C applications. The Q-SYS NS Series Gen 2 switch products are offered in 10-port and 26-port models. All Q-SYS
NS Series Gen 2 models offer 1 GbE (1000 Mbps) operation on their primary copper ports. That is, for 10 or 26 of their ports,
respectively. Additionally, all Q-SYS NS Series Gen 2 switches offer 1GbE and/or 10GbE uplinks via optional SFP (Small
Form-factor Pluggable) modules. All Q-SYS NS Series Gen 2 switches are PSEs (Power Sourcing Equipment) and are compliant
with IEEE 802.3af and IEEE 802.3at PoE and PoE+ (Power over Ethernet) standards, respectively. Additionally, PoE++ models
can deliver up to 90 Watts of IEEE 802.3bt Power over Ethernet. 10-port models feature 8 powered ports while 26-port models
feature 24 powered ports.
Every attempt has been made to ensure that the preinstalled switch configuration natively provides all prioritization and
management functions required for a typical Q-SYS installation, including common 3rd party devices, meaning these switches are
targeted as true plug-n-play applications. However, should the Q-SYS system installer need to adapt the switch configuration for
any reason, the QSC-supplied configurations provide default IP addresses and administrative credentials that allow a network
professional to access the Q-SYS NS Series Gen 2 switch products using a common web browser.
Recommended NS Series Gen 2 Network Deployments
The Q-SYS NS Series Gen 2 network switches provide a unique feature called IGMP Plus. This feature greatly simplifies system
architectures by enabling the same well-known IGMP techniques across the entire AV over IP (AVoIP) network. This enhanced
implementation for automatic multicast across a Layer 2 multicast network should require no user configuration when deployed in
the recommended manners shown below using supported Q-SYS AVoIP protocols and technologies.

Example A: Completely Isolated Systems
In this scenario, individual Q-SYS systems within a facility are completely isolated islands with their own dedicated networks and
no interaction with, or connection to, other systems or the facility’s infrastructure and services.
This scenario will work completely turnkey with no adjustments to the switches required.

Example B: Completely Isolated Systems with Switch Management
In many facilities with existing infrastructure and/or IT staff on hand, they may desire a connection to the AV switches for basic
monitoring or management. The Q-SYS NS Series Gen 2 switches feature an OOB (Out of Band) port that can be used for direct
access to the switch’s management functions without the need to connect to the AV network(s). This OOB port is configured for
DHCP and will fall back to 192.168.0.239 if no DHCP service is available. Note: It may take up to 5 minutes for the OOB port to
fall back to its default IP after initial power on or a reboot.
