The NETGEAR AV Line M4250 series was designed with input from AV Professionals. The result is a line of switches built from the ground up to support 1Gb audio and video over IP with customized hardware and software along with dedicated service and support.

NETGEAR M4250 series key features

• Ranges from 8 to 48 ports with a variety of PoE+ and Ultra90 PoE++ options for 15.4W, 30W, 60W, 75W and 90W AVoIP endpoints
• Uplink options include 1G for audio installations or standalone video installations as well as 10G uplinks for larger scale video deployments
• Also includes 12-port multi-gigabit Ethernet and 16-port 1G/10G fiber models for plug and play aggregation in a star topology
• Designed for a clean integration with traditional, rack-mounted, AV equipment
• The M4250 switches come with a sleek, black display panel with status in front and all cabling plus additional status in the back
• Reversed mounting is possible when ports are desired on the front of the rack
• A second pair of rackmount ears allows the switches to be mounted recessed by 2-inches to allow for the cabling
• Software-controlled fan adjustments enable the fans to be turned off when ambient temperature and PoE loads are appropriate for a totally fanless operation
• Threaded holes on the bottom (4xM5 for 50x100mm VESA) and in front (1xM10 for clamps) allow for universal mounting options outside the rack as well

NETGEAR M4250 series AV software features

• Pre-configured for audio and video over IP out of the box, the M4250 switches enable encoders and decoders to be connected with zero configuration
• When more configuration is required, an AV web-based GUI is available
• This interface has been specially designed for AV installers with specific AV-related controls made more accessible and with port-based profiles
• For audio, profiles for Dante, Q-SYS and AES67 are built-in, as well as an AVB profile (AVB license sold separately)
• For video, the M4250 offers profiles for NVX, SVSI, Q-SYS, NDI, Kramer KDS, Aurora Multimedia, ZeeVee, Atlona, Dante and SDVoE
• Other AV CODECs and manufacturers are supported as well as audio/video/ control mixed profiles
• To further simplify star deployments, NETGEAR IGMP Plus™ brings multicast automation between all M4250 switches, and with M4300/M4500
• With Auto-Trunk and Auto-LAG, simply connect M4250 switches together and you are done!

NETGEAR M4250 series other software features

• All M4250 switches share the same high-end NETGEAR Layer 2 / Layer 3 switching engine for a consistent experience
• All switches in the M4250 series have another main, IT web-based GUI for midsize Enterprise campus networks, IoT and IPTV
• Additional features include static, RIP and PIM-SM, DM and SSM multicast routing, DHCP Server and PTPv2 Transparent Clock (1-step E2E)
• AVB is the only feature requiring a license, all other advanced features are available license-free
• Advanced classifier-based, time-based hardware implementation for L2 (MAC), L3 (IP) and L4 (UDP/TCP transport ports) security and prioritization
• Selectable Port-Channel / LAG (802.3ad - 802.1AX) L2/L3/L4 hashing for fault tolerance and load sharing with any type of Ethernet channeling
• To further simplify star deployments, NETGEAR IGMP Plus™ brings multicast automation between all M4250 switches, and with M4300/M4500
• Voice VLAN with SIP, H323 and SCCP protocols detection and LLDP-MED IP phones automatic QoS and VLAN configuration
• Efficient authentication tiering with successive DOT1X, MAB and Captive Portal methods for streamlined BYOD
