AV-focused managed switch

The Netgear M4250 AV Line switch provides 40 PoE+ RJ45 ports and 8 SFP expansion slots for audio and video over IP deployments. It delivers a 480 W PoE budget with a single internal power supply consuming 59.50 W. The Layer 3 managed platform targets installers who need pre-configured profiles for Dante, Q-SYS, AES67, NVX, AMX, NDI and mixed AV traffic.

Gigabit uplinks and PoE ceiling

All 40 copper ports operate at 10/100/1000Base-T while the 8 SFP slots accept 1000Base-X modules for fiber uplinks. The 480 W PoE budget caps total powered-device draw, so dense 90 W endpoints cannot be fully populated. IGMP Plus automation links multiple M4250, M4300 or M4500 units without manual multicast tuning.

Rack or tabletop mounting

The 1U rack-mountable chassis includes ears for under-table or wall installation and rubber footpads for desktop use. Rear-facing ports keep cabling tidy in AV racks, and a C14 inlet accepts standard IEC power cords. Console access is provided via RJ45-to-DB9 and USB-C-to-USB-A 2.0 cables included in the package.
