Groundbreaking AV GUI A simplified user interface makes it easy to assign configuration profiles to each port. Multicast in an Instant NETGEAR IGMP Plus™ provides multicast functionality right out of the box for most AV over IP applications. Sleek, Quiet Design Less fan noise, and mounting ears included for rack mounting. Automatic Configuration Auto-trunk and auto-LAG functionality auto connects with other M4350 (and M4250) switches. FAST, EASY CONFIGURATION FOR AV PROS A streamlined interface enables factory default AV settings or user-specified AV profiles to be assigned to individual ports with just a few clicks. FOCUS ON THE EVENT NOT FAN NOISE Most models have quiet mode which greatly reduces fan noise. DESIGNED FOR AV OVER IP RIGHT OUT OF THE BOX With built-in NETGEAR IGMP Plus™, there's little-to-no setup required for flawless Video over IP delivery. Enable multicasting right out of the box.
