PoE issue with low power device (DOREMiDi MR-1 PoE) on Netgear M4250 switch
Hello,
I am experiencing an issue with PoE when using a Netgear M4250-9G1F-PoE+ switch together with a low power PoE device.
Setup:
- Switch: Netgear M4250-9G1F-PoE+
- Device: DOREMiDi MR-1 PoE (MIDI device)
- Power consumption of the device: approx. 1.5W
The problem is that the MR-1 PoE requires less power than the minimum PoE power delivered by the Netgear switch (minimum seems to be around 3W). Because the device draws so little power, the switch detects insufficient power consumption and automatically disables PoE on that port.
As a result, the device does not stay powered on when connected to the Netgear switch.
Interestingly, the same device works perfectly on a Cisco switch (Cisco LGS108P), where PoE remains enabled and stable.
My question:
Is there a way to configure the Netgear M4250 switch to support PoE devices with very low power consumption?
For example:
- A setting to force PoE on a port
- Adjusting PoE detection or minimum power thresholds
- Any recommended workaround or supported solution
I would appreciate any advice or guidance on how to resolve this issue.
Thank you in advance!

Ist this an assumption or backed from insight information available in the logs?
A IEEE standards compliant does start to provide power based on the pulsing or on LLDP packet sent from the powered device (PD) to the power source device (PSE).
The PoE controller should not terminate the power delivery on my opinion. even if the effective consumption is below 2.5W in my understanding.
A device requesting class 0 or class 1 is supposed to be able driving a PD consuming 0.44W-12.95W, with at least 15.4W at the PSE to overcome cable losses.
Unclear to me where the 2.5W data is coming from - have found this in a data sheet or a user manual?
