Netgear AV Line Managed Switch 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. The M4250 series ranges from 8 to 48 ports with a variety of PoE+ and Ultra90 PoE++ options. In addition, uplink options include 1G for audio installations or standalone video installations as well as 10G uplinks for larger scale video deployments. The M4250 series also includes 12-port multi-Gigabit Ethernet and 16-port 1G/10G fiber models for plug-and-play aggregation in a totally automated star topology. Designed for a clean integration with traditional rackmounted, 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 and a second pair of rackmount ears allows the switches to be mounted recessed 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 and in front allow for universal mounting options outside the rack as well.
