PRODUCT DESCRIPTION
NETGEAR M4250-40G8F-PoE+ 40-Port Gigabit PoE+ AV Line Managed Switch with 8 x SFP (GSM4248P-100EUS) - Limited Lifetime Local Warranty
40 PoE+ Ports, 480W, 8 SFP Uplinks
The NETGEAR GSM4248P (M4250-40G8F-PoE+) is a 48-port AV Line managed switch: 40 x 1G PoE+ ports and 8 x 1G SFP fibre ports. The 40 PoE+ ports deliver up to 30W each from a 480W PoE budget — ideal for large rooms and venues with many cameras, encoders/decoders, speakers and touch panels.
Pre-Configured for AV over IP
Out of the box the M4250 is set up for AV over IP. The AV user interface applies ready-made profiles for Dante, AES67, AVB, NDI, Q-SYS and more, while NETGEAR IGMP Plus handles multicast automatically with little-to-no setup, and auto-trunk and auto-LAG link switches together.
Fanless or Quiet Operation
The GSM4248P supports a fanless mode (0 dBA, quoted by NETGEAR at a 30W PoE load) and a quiet mode rated from 30 dBA at PoE loads up to 150W to 47 dBA at 340–480W (at 25°C) — suited to classrooms, meeting rooms, houses of worship and live venues.
Designed for Racks, Walls and Desks
The 1U chassis keeps the display panel on the front and all ports at the back. It ships with standard rack brackets, longer brackets for recessed (2-inch offset) mounting and rubber feet for tabletop use.

Compatibility & Software Support
AV User Interface
A dedicated AV user interface (AV UI), reachable over a network port or the out-of-band port, lets AV integrators apply ready-made profiles per port. The AV user manual lists pre-configured templates including Audio Dante, Audio AES67, Audio Video AVB, Audio Video AVB MILAN, Video NDI4, Video NDI5 / NDI6 with Dante, Q-SYS or AES67 audio, and Video with Dante, AES67 or Q-SYS audio. The datasheet names Dante, Q-SYS, AES67 and AVB audio profiles, and NVX, SVSI, Q-SYS, NDI and Dante video profiles.
Management Options
AV UI, the main web UI, CLI and SNMP, plus cloud management via the NETGEAR Insight Cloud Portal or Insight app (per the AV user manual). Out-of-band Ethernet management port, USB-C and RJ45 console ports, and a USB-A port for storage.
Multicast, AVB & Timing
NETGEAR IGMP Plus provides automatic multicast across an M4250/M4300/M4350/M4500 Layer 2 network. IEEE 802.1BA-2011 Audio Video Bridging (802.1AS, 802.1Qav, 802.1Qat, MSRP) is supported, as is a PTPv2 end-to-end transparent clock. AVB licensing: NETGEAR's product page lists an electronic AVB licence (AVB4248P-10000S); the AV user manual states that from firmware 13.0.4.17 a licence is no longer required for AVB.
Layer 2 / Layer 3 Features
4K VLANs, static routing, RIP, PIM-SM/DM, DHCP server, 802.1X, MAC authentication bypass, DHCP snooping, dynamic ARP inspection, L2/L3/L4 ACLs, private VLANs and 8 QoS priority queues.
