PRODUCT DESCRIPTION
NETGEAR M4250-40G8XF-PoE++ 40-Port Gigabit Ultra90 PoE++ AV Line Managed Switch with 8 x SFP+ (GSM4248UX-100EUS) - Limited Lifetime Local Warranty
40 Ultra90 PoE++ Ports, up to 2,880W
The NETGEAR GSM4248UX (M4250-40G8XF-PoE++) is a 48-port AV Line managed switch: 40 x 1G Ultra90 PoE++ (IEEE 802.3bt) ports delivering up to 90W each, plus 8 x 1G/10G SFP+ ports. With all three internal power supplies in use the PoE budget reaches 2,880W — enough to run 32 ports at a full 90W — for LED displays, PTZ cameras, video bars, thin clients and other high-draw AV devices.
Three Built-In Power Supplies
Three internal, fixed PSUs with an embedded RPS/EPS function scale the PoE budget: 720W with one PSU in use, 1,650W with two and 2,880W with three. The 2U chassis has side-to-side airflow and keeps the display panel on the front with all ports at the back.
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.
Quiet Mode for AV Spaces
NETGEAR rates the GSM4248UX at 30 dBA in quiet mode at PoE loads up to 160W, rising in steps to 60 dBA from 660W to the full 2,880W (at 25°C). Fanless mode is not supported on this model.

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 (AVB4248UX-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.

Frequently Asked Questions — NETGEAR GSM4248UX
How much PoE does the GSM4248UX provide?
40 Ultra90 PoE++ ports at up to 90W each. The total budget depends on how many of the three internal PSUs are in use: 720W (one), 1,650W (two) or 2,880W (three).
How many ports can run at 90W at once?
With all three PSUs powered, the 2,880W budget covers 32 ports at a full 90W simultaneously; lower-draw devices let you use all 40 ports.
Is the power supply redundant?
NETGEAR describes the three internal, fixed PSUs as having an embedded RPS/EPS function. Each has its own C14 inlet.
What uplinks does it have?
8 x SFP+ ports supporting 1G or 10G.
Can it run fanless?
No. NETGEAR lists fanless mode as not supported on the GSM4248UX; quiet mode starts at 30 dBA for PoE loads up to 160W.
Does AVB need a licence?
NETGEAR's product page lists an electronic AVB licence (AVB4248UX-10000S); the AV user manual states that from firmware 13.0.4.17 a licence is no longer required.
What warranty do I get?
Limited lifetime local warranty in Singapore, supplied by SourceIT with a GST invoice.
