MIC IP ultra 7100i showing ‘Low PoE’ and ‘Low PoE & Low 24VAC’ messages during login
Possible causes and solution(s)
Symptoms
When logging in to the MIC IP Ultra 7100i these warnings appear: 'Low PoE” and “Low PoE & Low 24VAC”
Camera is connected to a PoE capable switch
Camera is powered by an NDA-U-PSU2H 24 VAC power supply.
Causes
Low POE is caused by:
The technician likely intended to connect the camera over 24VAC but forgot to disable PoE on the switch.
Most switches provide 15W. Since the camera prioritizes POE, it first tries to use this.
This can result in an online camera without Pan Tilt.
To use only 24VAC, disable POE at the switch port.
In case POE is desired or for redundant connections, use the correct mid-span per the datasheet, noting if it requires an AT or BT standard midspan
Low 24VAC is caused by:
These messages appear because the power supply is insufficient. The NDA-U-PSU2H power supply is designed for AUTODOME cameras, not the MIC series.
Its output voltage is IEC 62638-1 Limited Power Source (24 VAC @ 3.5 Amps), unsuitable for the MIC IP ultra 7100i.
Solution
According to the camera’s datasheet, if powering the camera via a 24 VAC PSU this needs to be 24V at 100 volt-amperes which is approximately 4.17 Amps.
Replace the NDA-U-PSU2H with a 24 VAC/100 VA power supply suitable for the MIC IP Ultra 7100i.
Also, if powering via PoE, the camera must be powered via an official Bosch High PoE Midspan, not a generic PoE+ switch.
