Netgear Arlo power supply how can I identify potentially defective unit

[Joebannon]

Ladies gents. Appreciate this is not an Arlo product. I purchased 2017 an external netgear power supply unit. Post purchase I initially recived a product warning bulletin to which I responded to supplier. Since this I recived no further corrispindence as to how I can identify if the unit is potentially defective. I could not find any further details on the Netgear web site. Any idea if by serial number I can determine if this is a potentially defective units. BR.

If your talking about the external ac power supply for the cameras....

the model VMA4700 was recalled... the newer replacement is the 4900 ( look on the power supply for the model )
