Every port on the M4250-8G2XF-PoE+, explained
Click a card to light up those ports on the panels above.
8 PoE+ ports8 on the panel
Ports 1 to 8 are gigabit RJ45 with PoE+ for AV endpoints, cameras and touch panels. Each port can deliver up to 30 W, within the 220 W total.
2 SFP+ uplinks2 on the panel
Ports 9 and 10 take 1G SFP or 10G SFP+ modules. Use them to uplink to the main AV rack or to chain to another M4250.
USB-C console1 on the panel
A USB-C console port on the front for local CLI access from a laptop.
USB storage port1 on the panel
A USB-A port on the back for logs, packet captures, configuration files and firmware images.
Out-of-band management port1 on the panel
A 1G RJ45 service port on the back. Patch it to a separate management network so you can reach the switch even if the data ports are busy or misconfigured.
DC power input1 on the panel
The switch runs from an external power adapter, which plugs into the wall with a standard C13 AC cord. The DC jack is on the back.
- Front LEDs: Power, Fan and PoE Max.
- Reset button: on the front, next to the console port.
Power, PoE and fan modes
The 220 W PoE budget is shared by ports 1 to 8, enough for all eight ports at full PoE+ (8 x 30 W is 240 W, so plan on slightly less than that at once).
It ships with its own power adapter rated up to 254 W, which takes a standard C13 AC cord. The APS254W adapter is also sold separately as a spare.
- Fan off: at 25 C ambient the fans can stay off with up to 180 W of PoE load, when only the RJ45 ports are in use (no SFP+ modules).
- Quiet mode: 19.3 dBA at 25 C ambient.
- Cool mode: fans at full duty for hotter spaces, about 35.3 dBA.

M4250 AV profiles and the AV web interface
Every M4250 ships pre-configured for audio and video over IP, so encoders and decoders can be plugged in and work without setup. IGMP Plus is on by default on VLAN 1, which keeps multicast video from flooding the network.
- AV web interface: browse to the switch's IP address on port 8080 for the AV-specific settings. The regular IT web interface and a CLI are there too.
- Audio profiles: Dante, Q-SYS, AES67 and AVB are built in.
- Video profiles: NVX, AMX, Q-SYS, NDI, Kramer KDS, Aurora Multimedia, ZeeVee, Atlona, Dante, SDVoE and more, plus mixed audio, video and control profiles. Profiles are color coded and applied per port.
- Switch-to-switch links: with Auto-Trunk and Auto-LAG, two M4250s connected together trunk their VLANs and bundle multiple links automatically.
- Fleet management: the NETGEAR Engage controller manages M4250, M4300, M4350 and M4500 switches together.
M4250 management ports
All M4250 models share the same set of management ports, though where they sit (front or back) depends on the model.
- Console: an RJ45 RS232 straight-through serial port and a USB-C console port, for local CLI access.
- Out-of-band Ethernet: a 1G service port for a separate management network.
- USB-A storage: for logs, packet captures, configuration files and firmware images.
- Dual firmware: two firmware images and two configuration files, so updates cause minimal downtime.
Mounting and fan modes
- Rackmount models can be mounted reversed when you want the ports facing the front of the rack. A second, included pair of ears sets the switch back 2 in. (about 5 cm) to leave room for cables.
- Threaded holes underneath (4 x M5 on a 50 x 100 mm VESA pattern) and on the front (1 x M10 for clamps) allow mounting outside a rack.
- Desktop models are meant for conference rooms, mobile studios, under a table or behind a screen, and mount with side flanges.
- Fans are software controlled. Most models can switch the fans off entirely when the room temperature and PoE load are low enough, and offer Quiet and Cool modes otherwise. The M4250-9G1F-PoE+ is fanless.
Fan-off mode depends on ambient temperature and PoE load. Check your model's limits before closing it inside a cabinet or ceiling space.
