When a user is using the Dell Speakerphone with Multiport Adapter MH3021P, they have the option of having it powered by the computers (USB Type-C).
You can also provide power by attaching the computers AC power adapter to the speakerphone directly. When the user attaches the AC power adapter to the speakerphone itself, the speakerphone reserves 15w of power for itself. This lowers the amount of power that is transferred to the computer during use.
This may generate an undersized power adapter error during post or while in Windows.
Example: user attaches 90w adapter to the MH3021P speakerphone, it reserves 15w for itself and transfer 75w to the computer.
|Power Source Plugged into MH3021P||Power to Laptop**|
Users do not have to provide dedicated power to the speakerphone but get additional functionality from the MH3021P speakerphone if they do. When the MH3021P speakerphone has an AC adapter that is connected, it also becomes a powered USB hub to power devices such as USB hard drives.
Without the AC adapter that is connected to the MH3021P speakerphone, the USB ports on the speakerphone can only power keyboards, mice, USB memory keys, and such.
